+## Slots
+
+* `placeholder`: Only shown when nothing is selected
+* `loading`: Hidden by default, shown instead of items while `populate()` runs
+
+## Parts
+
+* `display`: The outer display box that is always shown
+* `display-text`: The text representing the currently selected value
+* `drop-down`: The dialog element that pops up when the list is opened
+* `search`: The search input box
+* `list`: The wrapper containing the items
+* `item`: The individual selectable list items
+
+## Hooks
+
+* `populate()`: If present, gets called after opening to populate the options list
+* `search(string)`: Called on search input to update the list of options
+* `match(string, element)`: Used by `search` to compare each option to the search string
+
+## Attributes
+
+* `closeSignal`: An AbortSignal that fires when the drop-down closes
