mui | High-performance framework closest to native APP experience

I have created a responsive stage using react-konva, but I cannot find a way to set a custom size to export the image. usually, right-click and saving the image is working as the size in the window at that time has. I wanted to add a button to download the image, but I couldn't set up a way to do that because I'm new to react hooks, I couldn't find a way to set up the data URL. please kindly refer to this

I'm trying to apply a custom MUI theme using a context provider, but the theme is not being applied in child components.

Here is my palette code:

Is anyone using Vite to bundle their MUI app? I was surprised at how big my vendor chunk (1.1MB) was from Vite/Rollup. I've come up with the below config which separates MUI packages into it's own chunk:

I just started using Material UI 5.0.4 (with styled-components), and I wanted to access the theme in a component. I looked online and saw useTheme, so I checked the docs and found it - @mui/styles/useTheme. However, it was the legacy documentation, and @mui/styles does not exist in MUI 5. So, I looked at @mui/system instead, and found the section "Accessing the theme in a component". However, this just points back to the legacy documentation!

After the docs didn't seem to help me, I decided to use Visual Studio Code's "Quick Fix" feature, where if you hover over the function, VSCode will give you a list of options to import. Here is the list of options I tried, and why they didn't work:

• @mui/material/styles/useTheme - Returns the default theme object, no matter what. Looking into the source code, this is literally what it does - it switches to the default theme, and then returns the theme.
• @mui/material/private-theming/useTheme - This just returns null. I feel like I shouldn't be accessing this anyway (it says private-), but I tried it anyway.
• @mui/system/useTheme - This is what I was hoping would work. However, this is also probably the weirdest one. It gives me the default theme, but it excludes many properties. For example, it only provided palette.mode, and there are no other keys under palette than that. (You can see the whole thing below)

I have installed both @material-ui/core and @material-ui/icons.

I am trying to import "FileDownloadIcon" from Material icons.

I'm creating a custom dynamic form using Material UI https://mui.com/ library as the component for my React Js app.

Here is the initial state of the dynamic form component.

As we can see that the dynamic form component starts only with one delivery point form. We could add another delivery point form by clicking the "Add Delivery" button. Here is the example after clicking the "Add Delivery" button.

The problem is: the first form and the second form have the same values (if there are more than 1 form) after we gave input to one of the first or second forms as seen in the screenshot below. This is not the condition I want.

But the rest (third, fourth, and so on) forms are unique as seen in the screenshot below. This is the condition I want.

Here is the simple working code:

DeliveryPoint.jsx

The component is not rerendering after the deletion of an element in the state but the state does change. In the component, you can add an element in the array (which is a state) through form, see all the elements in the array, and delete it from the state using the button. So after deleting an element that is in the state, the component does not rerender. Following is the code of the component:

I'm currently using Material UI for a personal project, but I suppose this is a more general question about tables. I have a figma layout I made that I think looks nice, but I'm not quite sure how to implement it.

Currently I have a MUI table, but there's two issues. One, I don't know how to make the very top 3 headers a part of the table, I can manually position them but if you resize a screen they will move out of position from the table contents. Two, how the heck can I section a table like this? To have the table headers justified left in sections?

It's been a frustrating day to work on this, while I was designing this felt like a normal table design, but I can't figure out how the heck to section into three parts.

Here is my current code:

I was using the Material UI Timepicker but after updating to MUI 5 it is not working anymore. I updated everything to @next and @material-ui/core (version 5.0.0-beta.5) and @material-ui/lab (version: 5.0.0-alpha.44).
