I have in React an accordion with buttons that slide up/down content, like on this image

I made some functional components and things look like this:

I'm trying to filter different posts kinda page. Each post has many different categories. But the search filter is two-layered, the main filter and then below a more specific selection of filters where I used checkboxes. The problem is that all categories are on the same level. How can I access each selected class based on the user filter input and then output the right post?

Categories and their classes are listed like this:

I am working on a Bootstrap use case. I have designed a menu using Bootstrap. I want the menu to be hidden when I scroll down, and the menu to be displayed if I scroll up. (slide-down / slide-up).

I want to use jQuery to for this functionality.

I have a div containing a button that has some continues animation on it, not just on hover, the whole button is just animated. Then I have a "LOAD MORE" button beneath it, using JavaScript it would load the next div which contains exactly the same button (with animation). Problem is since the 2nd div is display:none till the load more button is clicked, the animation starts at the time the load more button is clicked and therefore becomes inconsistent the the animation of the same button above it. I guess the question is, how do I keep my CSS animation playing in the background of the display:none div so that when its loaded the animation starts at the same time and matches the shown button?

here is a direct link to where the issue is happening, please click LOAD MORE and notice the difference that happens in the CSS animation: LINK TO ISSUE (LIVE)

please see the link above // the first 4 buttons are set to be visible, so the CSS animation on them are consistent. When I click LOAD MORE, the 5th button with was in div with display:none is now visible but starts the CSS animation at different time!! how do I have it load at the same time?

i am doing a toast that notifies admin about events happening in firestore but when i reload the web page the added event is called with the same number of documents?

I'm trying to receive data on the client-side from the controller using ajax, but what is happened is I received data and it shows in the table when I using complete function in ajax but when I use success function the data did not show in the table. From what I know the success function start earlier than the complete function, I want to use success to show some alert, If I put success alert in complete function it will display even when error function is executed.

when I put both functions complete to return data and success to show the alert the data did not show in the table

I'm developing a tinderlike swipe app for babynames. I've created a method that, when you click a button besides one of your favorite names, it pops up a window (A UIViewController with a WKWebView) that shows a google search with the meaning of this particular name.

The problem is that with some names, the app crashes because the URL returns nil. I don't understand what's happening, because other names are working just fine. I've found out it happens with Scandinavian names like "OddVeig" and "OddLaug" .

Below is my UIViewController class that pops up with the search result (I've put all the initializing code in the layoutSubViews(), because I had some trouble in iOS 12, where the WKWebView wouldn't resize properly if I put it in the viewDidLoad() ) :

What I want, when I click on the login button of the first activity the yellow part slides down and the next activity opens. when I click on the signup button of the second screen(login screen) the yellow part of the second screen slides up and the first activity (sign up Activity)opens. I have used slide-down animation on the linear layout on the first screen it works but not working smoothly, I think because of intent. how I did this

After doing some research I came to this code shown below. If you try the code yourself you notice the variable is used for every div with a button and text (the whole site). I tried several other codes but I like the slideDown/Up feature.
