A sidebar combo (dropdown+list) is like this:
<div class="issue-sidebar-combo" data-selection-mode="..." data-update-url="...">
<input class="combo-value" name="..." type="hidden" value="...">
<div class="ui dropdown">
<div class="menu">
<div class="item clear-selection">clear</div>
<div class="item" data-value="..." data-scope="...">
<span class="item-check-mark">...</span>
...
</div>
</div>
</div>
<div class="ui list">
<span class="item empty-list">no item</span>
<span class="item">...</span>
</div>
</div>
When the selected items change, the combo-value input will be updated.
If there is data-update-url, it also calls backend to attach/detach the changed items.
Also, the changed items will be synchronized to the ui list items.
The items with the same data-scope only allow one selected at a time.
The dropdown selection could work in 2 modes:
- single: only one item could be selected, it updates immediately when the item is selected.
- multiple: multiple items could be selected, it defers the update until the dropdown is hidden.
When using "scrolling menu", the items must be in the same level, otherwise keyboard (ArrowUp/ArrowDown/Enter) won't work.
