Proposal

Please re-state the problem that we are trying to solve in this issue.

Sticky header overlaps scroll bar.

What is the root cause of that problem?

The Sticky header from FlashList overlaps scroll bar.

The 1st part of the scroll bar is overlapped and user can't click on it.

What changes do you think we should make in order to solve the problem?

Change the style of the StickyHeader children (because we don't have access to style the StickyHeader div) to give space for the scroll bar.

<View  style={[styles.emojiHeaderContainer, target === 'StickyHeader' ? styles.stickyHeaderEmoji : undefined]}>

where StickyHeader is:

stickyHeaderEmoji: {
	position:  'absolute',
	width:  '-webkit-fill-available',
	...spacing.mh4,
},

POC

007.mp4

[dragnoir]

To support all browsers we can use the below:

  width: '100%',
  width: '-webkit-fill-available',
  width: '-mos-available',
  width: 'fill-available',

Can repro, let DB know in #vip-vsb here

Proposal

Please re-state the problem that we are trying to solve in this issue.

Instead of scrolling down the performed action results in selecting the emoji categories

What is the root cause of that problem?

The emoji picker header is defined here. It's wrapped into the absolute container

Because this container has 320px width that makes the scroll bar is overlapped -> We can't click on scroll bar

What changes do you think we should make in order to solve the problem?

Seem like we don't have any direct ways to access the header container so we should change the style of the StickyHeader itself.

1. Add position: 'absolute' to StickyHeader, so the parent will be ignored
2. The width of EmojiPicker on large screen is 320px and 100% on small screen. The width of StickyHeader would be width of EmojiPicker - 32 (32 = marginLeft + marginRight)

so we can calculate the style for StickyHeader as below:

position: 'absolute',
width: isSmallScreenWidth ? windowWidth - 32: 288,
...styles.mh4,

What alternative solutions did you explore? (Optional)

NA

[dragnoir]

@tienifr you are copying my proposal. You're just trying to calculate width with js.

[tienifr]

you are copying my proposal

@dragnoir, I don't think so. The RCA is easy to figure out, the hard part is finding the solution. I believe the best way is to fix StickyHeader's parent style but I can't find it on the documentation. If someone can find the simple way to override the parent style, I believe it will be chosen as the best solution.

You're just trying to calculate width with js

I don't think your solution is good. -webkit-fill-available does not work with all platforms, and width: 100% will break the advantage of styles. mh4. That why I think calculating the width will be better. Let's wait to hear @rushatgabhane's review

[dragnoir]

@tienifr the hard part is how to override the parent absolute position without having access to it.
Assigning absolute position to a child is my idea and the 1st who mentioned it. You jsu calculated width in a different way.

I also mentioned how to make fill for all browsers.

[dragnoir]

@rushatgabhane @jliexpensify I am a new contributor and it's mentioned here

Note: Before submitting a proposal on an issue, be sure to read any other existing proposals. ALL NEW PROPOSALS MUST BE DIFFERENT FROM EXISTING PROPOSALS. The difference should be important, meaningful or considerable.

Also I was watched lots of proposals and I am sure details like how to handle or how the team prefer to calculate width can be discussed throw PR. (Unless the proposal is wrong and it's not the case here)

In my propsal I figured our the route cause problem and as you can see here lots of other developers was not able to figure out how to style the StickyHeader and how to eliminate the absolute position.
My solution, assigning absolute to a child to override the width of an absolute parent, is the main key to solve the issue. And I am sure the second proposal difference is not important, meaningful or considerable as mentioned in the contribution guide.

[tienifr]

-webkit-fill-available does not work with all platforms

@dragnoir Please read my comment carefully 🙏 . How do you know fill-available works for all platforms? I don't see any places in our App (or docs) do like that, it's quite messy.

width: 100% will break the advantage of styles.mh4

Did you check this? I believe putting width: 100% will break the current behavior. I appreciate your time you spent here but I don't agree that you said my change is not important. Your solution doesn't work (width: 100%), so I suggest the way that works for all platforms, why isn't it important?

We're trying to build the supportive society, I'm also glad to colab with you in this issue if my solution is chosen. For now, just wait to hear C+ review. Thanks

[dragnoir]

I believe putting width: 100% will break the current behavior.

Please check how CSS Overriding works.
