                                                                                  I have made a dropdown menu using Material-ui Menu component. The problem is once that dropdown menu is open, the body scrollbar disappears and can not scroll over the page.

                                                                                  I tried to find answers but there are only a few answers for Popper, Popover or Select component but seems like no answer for Menu component.

                                                                                  DropDownMenu component is like this.

                                                                                  I have a image field, and I want this file to be required only when image_old field is empty and poster_type is image.

                                                                                  Here, the poster type is a select box with two possible value script or image. Next, image_old holds file name like picture.png, this is the value of poster image, and this will have value only in case of edit. (Its becauuse, I am using the same component for create and edit)

                                                                                  My code looks like:

                                                                                  I am trying to make a chat application with scaledrone. I was following this tutorial: https://www.scaledrone.com/blog/javascript-chat-room-tutorial/ but after setting up the basic chat, I wanted to let users define their own name. So I made an input box and then tried using js to take the input box value and assign it to a variable. And then for the name part of the chat application, instead of using the random name function I was using earlier. However, I got the error "can not read properties of null(reading addEventListener) in my console and the submit button did not show up at all. What did I do wrong? The code I used is in pastebin links below. The scaledrone documentation is here: https://www.scaledrone.com/docs/api-clients/javascript Thanks in advance. also, I added the raw text of my javascript file below because stack overflow won't let me post without adding some code(first time posting to stack overflow lol).

It depicts a European girl wearing an exotic dress, an oriental turban, and what was thought to be a very large pearl as an earring. In 2014, Dutch astrophysicist Vincent Icke raised doubts about the material of the earring and argued that it looks more like polished tin than pearl on the grounds of the specular reflection, the pear shape and the large size of the earring.",

Rousseau first exhibited the painting at the 13th Salon des Indépendants, and tried unsuccessfully to sell it to the mayor of his hometown, Laval. Instead, it entered the private collection of a Parisian charcoal merchant where it remained until 1924, when it was discovered by the art critic Louis Vauxcelles.",

The interior depicted is the Café de la Gare, 30 Place Lamartine, run by Joseph-Michel Ginoux and his wife Marie, who in November 1888 posed for Van Gogh's and Gauguin's Arlésienne; a bit later, Joseph Ginoux evidently posed for both artists, too.",

The painting is particularly remarkable for its creative composition, which rejected realistic representation in favour of distorting objects to create multiple perspectives. This approach eventually influenced other art movements, including Fauvism and Cubism. It belongs to the Helen Birch Bartlett Memorial Collection of the Art Institute of Chicago.",

For this use the first routing snippet so they are independent routes and not nested.

                                                                                  Next, the reason the next painting's urlPath is being appended as /galleria/Girl-with-a-Pearl-Earring/The-Great-Wave-off-Kanagawa is because react-router-dom v6 is capable of using absolute and relative paths. The difference between them is a leading "/" character. Paths starting with "/" are absolute paths, and without are relative.

                                                                                  Within Paint the next/previous buttons/links are specifying only the next/previous data[index].uriPath value instead of including the "/galleria" absolute path prefix.

                                                                                    A relative value (that does not begin with /) resolves relative to the parent route, which means that it builds upon the URL path that was matched by the route that rendered that . It may contain .. to link to routes further up the hierarchy. In these cases, .. works exactly like the command-line cd function; each .. removes one segment of the parent path.

                                                                                  I have a parent div that needs to handle for draggable events (such as when a file is dragged over it). When onDragEnter is invoked, I want the background color to change. However, I have a child div, which, when hovering over it, invokes the parent div's onDragLeave event. I've tried using a ref with this child div to determine if the event target is contained in the child div but that doesn't seem to be working. How can I avoid a child div in React invoking the onDragLeave event? Thanks!

                                                                                  The simplest way to do this would be to set pointerEvents: "none" in the style prop of the child

                                                                                  , so that all pointer-related events on this div are ignored. That would introduce some limitations, though - like you couldn't bind click events to the child div.

                                                                                  If this doesn't fit within the constraints of your application, you can modify your onDragLeave handler to inspect the relatedTarget of the event (see docs). If the drag is leaving the parent

                                                                                  but entering a child of the parent, then the relatedTarget (i.e. child div), will be contained (see docs) by the currentTarget (i.e. the parent )

                                                                                  Here's the code that should work:

                                                                                  const onDragLeave = (event) => {
                                                                                      preventDefaults(event);
                                                                                      // This condition will be true when the drag leaves the parent for a child,
                                                                                      // but false when the drag leaves the parent for somewhere else.
                                                                                      if (event.currentTarget.contains(event.relatedTarget)) return;

In my case, I am just using the md columns to keep things simple like so:

                                                                                  This kinda depends of what your page is looking like. The fastest is to try some variants of 100vw in smaller resolutions and some absolute values like 600px as you would normally do while doing some responsive.

                                                                                  Toggle your devtools and look how this is rendered with the emulated values, like this pretty much.

The child is not allowed to change its parents state, if a child wants to change a parents state then the parent passes a callback to the child that the child can call to change the state. This is fundamental to reacts state management. A child does not need to know how a parent stores it’s state (class instance, hook instance or state library).

                                                                                  if your application uses a global state manager like redux, then global state is mapped to props and a store action can be called to update global state. In this case the child does not need to know who else is using the state because it’s global.
