Wildmenu Events *ui-wildmenu*
Only sent if `ext_wildmenu` option is set in |ui-options|
["wildmenu_show", items]
When `ext_wildmenu` is set to true, nvim will not draw the
wildmenu on the grid, instead when the wildmenu is to be displayed
this update is sent. `items` is an array of the completion items.
["wildmenu_select", selected]
An item in the currently displayed wildmenu is selected. `selected`
is either a zero-based index into the array of items from the last
wildmenu event, or -1 if no item is selected.
["wildmenu_hide"]
The wildmenu is hidden.
