Follow: * #23345 The branch/tag selector dropdown mixes jQuery/Fomantic UI/Vue together, it's very diffcult to maintain and causes unfixable a11y problems. It also causes problems like #19851 #21314 #21952 This PR is the first step for the refactoring, move `data-` attributes to JS object and use Vue data as much as possible. The old selector `'.choose.reference .dropdown'` was also wrong, it hits `<div class="choose reference"><svg class="dropdown icon">` and would cause undefined behaviors. I have done some quick tests and it works. After this PR gets merged, I will move the code into a Vue SFC in next PR. ![image](https://user-images.githubusercontent.com/2114189/224099638-378a8a86-0865-47d1-bcba-f972506374c7.png) ![image](https://user-images.githubusercontent.com/2114189/224099690-70276cf5-b1e4-404a-b0c6-582448abf40e.png) --------- Co-authored-by: techknowlogick <techknowlogick@gitea.io>
