AEM- New (Tag Tree) Tab in Sidekick
This post is on adding a new tab to the Sidekick. Here we extend Sidekick and add a new tab showing CQ Tag Tree. To add new tags or remove tags for a page, multiple clicks are involved in opening Sidekick -> Page Tab -> Page Properties -> Basic -> Tags
If adding and removing tags is a common use-case in your project, adding the tag tree in a sidekick tab could be useful and saves some clicks. The new tab loads a checkbox tree; to add a tag check the box and to remove uncheck. If a tag is checked, parent tags are shown in bold to identify the tags checked, deep down in the tree. Source code, demo video and package install are available for download
I hope this will help you.
Thanks and Regards
