Dock in JavaScript (ES5) Sidebar control

08 May 2023 / 1 minute to read

Dock state of the Sidebar reserves some space on the page that always remains in a visible state when the Sidebar is collapsed. It is used to show the short term of a content like icons alone instead of lengthy text. To achieve this , set enableDock as true along with required dockSize.

In the following sample, the list item has icon with text representation. On dock state, only icons in list will be visible to represent the hint of the hidden text content.
