Popover menu
What is a popover menu
This is a quick menu that open on click. For menus, we use the three-dot-icon.
This is exactly the same as the navigation menu. The only difference is the popovermenu class.
Basic layout
 
<div class="popovermenu">
    <ul>
       <li>
           <a href="#" class="icon-details">
               <span>Details</span>
           </a>
       </li>
       <li>
           <button class="icon-close">
               <span>Remove</span>
           </button>
       </li>
       <li>
           <button>
               <span class="icon-favorite"></span>
               <span>Favorite</span>
           </button>
       </li>
       <li>
           <a>
               <span class="icon-rename"></span>
               <span>Edit</span>
           </a>
       </li>
       <li>
           <span class="menuitem">
               <input id="check1" type="checkbox" class="checkbox" />
               <label for="check1">Enable</label>
           </span>
       </li>
       <li>
           <span class="menuitem">
               <input id="radio1" type="radio" class="radio" />
               <label for="radio1">Select</label>
           </span>
       </li>
        <li>
            <span class="menuitem">
                <span class="icon icon-user"></span>
                <form>
                        <input id="input-folder" type="text" value="new email">
                        <input type="submit" value=" " class="primary icon-checkmark-white">
                </form>
            </span>
        </li>
         <li>
             <span class="menuitem">
                 <span class="icon icon-folder"></span>
                 <form>
                         <input id="input-folder" type="text" value="New folder">
                         <input type="submit" value=" " class="icon-confirm">
                 </form>
             </span>
         </li>
    </ul>
</div>
Technical details
- The only allowed menu items elements are a, button and span for the checkbox and radio only. 
- You can mix between a and button on the same menu (in case of form or direct link) like the example above 
- You need to put the entire menu just after the three dot icon - <div><span class="icon-more"></span><div class="popovermenu">...</div></div>
- You do not need JS, CSS only is ok for positioning. JS is still required to handle the hide/show. 
- Only one ul is allowed. 
- Only one level of menu is allowed. 
- Every entry needs to have its own icon. This greatly improves the UX. 
- The required right distance to the border (or padding, whatever you want to use) of the three-dot icon should be 14px (5 for menu margin and 6 for arrow position) 
- The - spanelement must have the- menuitemclass.
- The checkbox/radio must use the nextcloud custom 
- The form element is optional if you’re using inputs. 
- Supported inputs are all text based ones and buttons type ones 
 
Alignment
If you want to align your menu, you can add the class to the main popovermenu div.
- Center: - menu-center
- Left: - menu-left
- Right is by default
