# DisclosureMenu
|
|
|
|
A component to be used for making dropup/down/left/right menus i.e. Disclosure
|
|
Menus. Please see both Disclosure and Menu components for more details.
|
|
|
|
The component does not make any guesses around whether you want the panel to
|
|
be on another DOM layer/absolutely positioned so you should apply that layout
|
|
yourself, but it's root node is relatively positioned to help for the fairly
|
|
common usecase of having a floating menu.

`DisclosureMenu` also supports virtually scrolling its menu items for when you have 1000s of items to display in the menu whilst avoiding DOM stuttering. The set up is a tinsy bit more involved. but eesnetially you provide the data items for the menu using the `@items` argument, and then you can loop through these in the menu to make/use your menu items. The `menu.items` property is automatically paged for you depending on the scroll position of the menu panel. Importantly, right now, you should provide a height value for each menu.item using the `--paged-row-height` CSS property, you can do this inline or within your CSS (preferred). If you don't do this the component is unable to calculate the size of the scroll track/thumb. In the future (when needed) we will provide a callback for each item so you can specify a function to calculate the size of each individual item to give us a little more flexibility on what we can do with this component.
