Use design tokens in GlCollapsibleListbox

Purpose

As part of implementing design tokens across the product, we need to update each component to use design tokens. This issue focuses on the GlCollapsibleListbox component from gitlab-ui.

References

• Token specification
• Vue component
• Figma component
• Total adoption scanner findings: 195

Outcome

• Update the Figma Library to use the new tokens
• Update the component implementation to use the new tokens

Note

Design tokens on GlCollapsibleListbox are shared with GlDisclosureDropdown and dependant on action semantic design tokens being implemented (likely with GlButton)
