Why is 4c5e17dc9ff66a401874a161a8f3ea3c65904a4d in this PR?

[bandinib-amzn]

Can we rebase this PR to main?

[bandinib-amzn]

Why we choose option 2 and option 4? If they are default values, can we store them in constant and add comment so that in future if want to decide change the default values it will be easier for other developers?

[AbhishekReddy1127]

These examples are just to demo icon prop usage, I think moving to common won't be the right thing because consumers when use the example will also need to be aware and refer to common code stored which would be else where.

[bandinib-amzn]

Code from Line 16 to Line 80 is same in both combo_box_custome_icon.js and combo_box_default_icon.js. Is it possible to reuse the code?

[AbhishekReddy1127]

These changes are just for demonstration purpose, examples on how to combo box with custom icon and and default search icon.
It not basically part of actual implementation. If we re-use then i think the example snippet will be disturbed...

[AMoo-Miki]

I remember seeing some of these sample codes shared between examples. We could look at combining them after merging this PR.

[bandinib-amzn]

Let's create an issue to refactor this code and avoid duplication and reuse examples. Approving this PR.

The backport to 1.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/backport-1.x 1.x
# Navigate to the new working tree
pushd ../.worktrees/backport-1.x
# Create a new branch
git switch --create backport/backport-660-to-1.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 af0883cb0b87fe93fb3f6c6bd5aaafc8014880c0
# Push it to GitHub
git push --set-upstream origin backport/backport-660-to-1.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-1.x

Then, create a pull request where the base branch is 1.x and the compare/head branch is backport/backport-660-to-1.x.
