Examples

Default

<%= render(Primer::Dropdown.new) do |c| %>
  <% c.button do %>
    Dropdown
  <% end %>

  <% c.menu(header: "Options") do |menu|
    menu.item { "Item 1" }
    menu.item { "Item 2" }
    menu.item { "Item 3" }

With dividers

Dividers can be used to separate a group of items. They don't have any content.

<%= render(Primer::Dropdown.new) do |c| %>
  <% c.button do %>
    Dropdown
  <% end %>

  <% c.menu(header: "Options") do |menu|
    menu.item { "Item 1" }
    menu.item { "Item 2" }
    menu.item(divider: true)
    menu.item { "Item 3" }
    menu.item { "Item 4" }
    menu.item(divider: true)
    menu.item { "Item 5" }
    menu.item { "Item 6" }
  end %>
<% end %>

With direction

<%= render(Primer::Dropdown.new(display: :inline_block)) do |c| %>
  <% c.button do %>
    Dropdown
  <% end %>

  <% c.menu(header: "Options", direction: :s) do |menu|
    menu.item { "Item 1" }
    menu.item { "Item 2" }
    menu.item { "Item 3" }
    menu.item { "Item 4" }
  end %>
<% end %>

With caret

<%= render(Primer::Dropdown.new(with_caret: true)) do |c| %>
  <% c.button do %>
    Dropdown
  <% end %>

  <% c.menu(header: "Options") do |menu|
    menu.item { "Item 1" }
    menu.item { "Item 2" }
    menu.item { "Item 3" }
    menu.item { "Item 4" }
  end %>
<% end %>

Customizing the button

<%= render(Primer::Dropdown.new) do |c| %>
  <% c.button(scheme: :primary, size: :small) do %>
    Dropdown
  <% end %>

  <% c.menu(header: "Options") do |menu|
    menu.item { "Item 1" }
    menu.item { "Item 2" }
    menu.item { "Item 3" }
    menu.item { "Item 4" }
  end %>
<% end %>

<%= render(Primer::Dropdown.new) do |c| %>
  <% c.button do %>
    Dropdown
  <% end %>

  <% c.menu(as: :list, header: "Options") do |menu|
    menu.item { "Item 1" }
    menu.item { "Item 2" }
    menu.item(divider: true)
    menu.item { "Item 3" }
    menu.item { "Item 4" }
  end %>
<% end %>

<%= render(Primer::Dropdown.new) do |c| %>
  <% c.button do %>
    Dropdown
  <% end %>

  <% c.menu(header: "Options") do |menu|
    menu.item(tag: :button) { "Item 1" }
    menu.item(classes: "custom-class") { "Item 2" }
    menu.item { "Item 3" }
  end %>
<% end %>
