| # Element: Totem Indicator | ||
| Handles the updating and visibility of totems. | ||
| ## Widget | ||
| Totems - A `table` to hold sub-widgets. | ||
| ## Sub-Widgets | ||
| Totem - Any UI widget. | ||
| ## Sub-Widget Options | ||
| .Icon - A `Texture` representing the totem icon. | ||
| .Cooldown - A `Cooldown` representing the duration of the totem. | ||
| ## Notes | ||
| OnEnter and OnLeave script handlers will be set to display a Tooltip if the `Totem` widget is mouse enabled. | ||
| ## Examples | ||
| local Totems = {} | ||

| -- Position and size of the totem indicator | ||
| local Totem = CreateFrame('Button', nil, self) | ||
| Totem:SetSize(40, 40) | ||
