For svelte-based content, the default is "force". For HTML and Handlebars content, the default is "handlebars".

An optional array of CSS classes to apply to the tab contents container.

The required static ID associated with a tab.

Remarks

A tabId is a unique string of text that identifies your tab. It needs to be in a format that can be put into an HTML attribute. The tab ID is always required to register a tab.

A tabId must be unique to the target sheet. For example, the character sheet can only have one "my-module-id-my-spellbook-tab" ID, and the NPC sheet can also only have one "my-module-id-my-spellbook-tab" ID, etc.

Advice for crafting a unique tab ID:

• for modules, use your module ID as a prefix (e.g., "my-module-id")
  • for world scripts, use your game world name (e.g., "my-game-world")
• add a hyphenated version of the tab title (e.g., for a tab titled "My Spellbook Tab", use "my-spellbook-tab")
• join these two pieces together with a hyphen:

"my-module-id-my-spellbook-tab"
