reagent-contextmenu

Context menu components for Reagent.

Takes care of all the little details for creating a context menu.

(Compatible with Bootstrap; already uses UL and LI elements along with the dropdown-menu class.)

Install

Add this to your project dependencies:

The Bootstrap CSS is recommended if you don't want to style the menu yourself, along with contextmenu.css (especially for submenus).

Usage

Include the context-menu component in the root of your document:

(defn main-page []
	[:div
	  [:h1 "Page title"]
	  [:span "Some content"]
	  [menu/context-menu]]) ;  <-------

Everytime you want to show a context-menu to the user, you just need to call context! by passing it the :on-context-menu event and the name-function collection.

Name-function pairs should be of the following form: [name fn]. If fn is nil, the menu will mark this item with the disabled class.

If you replace the name-fn by a keyword, it will place a divider.

Finally, you if replace the name-fn by a string, it will be considered a section heading.

Note that the name can be any Reagent component.

[:div {:on-context-menu
       (fn [evt]
         (menu/context! 
          evt
          ["Some title"             ; <---- string is a section title
           ["my-fn" #(prn "my-fn")]
           [[:span "my-other-fn"] #(prn "my-other-fn")] ; <---- the name is a span
           :divider                    ; <--- keyword is a divider
           [[:span 
             [:span.cmd "Copy"] 
             [:span.kbd.text-muted "ctrl-c"]] ; <--- some classes to show a keyboard shortcut
            #(prn "Copy")]
           ["Submenu" 
            ["Submenu title" ["Submenu item 1" #(prn "Item 1")]]]]))}] ; <-- submenus are simply nested menus.

You can style your context menu with CSS and the class context-menu.

Pressing Esc or clicking outside the context-menu will hide it.

The backdrop, which is transparent by default, can be styled using the class context-menu-backdrop.
