Hi @Abirami_SD,
Tagfield makes use of foundation-autocomplete where picker is configured as part of attribute named pickersrc.
Value of pickersrc being - /mnt/overlay/cq/gui/content/coral/common/form/tagfield/picker.html?root=%2fcontent%2fcq%3atags&selectionCount=multiple where root and selectionCount is dynamic and can be set using properties on resource where tagfield is used
- root is set with value from property named rootPath
- selectionCount is set with value from boolean property multiple
For tagfield within search facets, per the logic written in /libs/cq/gui/components/coral/common/admin/customsearch/searchpredicates/tagspredicate/tagspredicate.jsp(resource used in below tags node via sling:resourceType), we can either use rootPath or tagsPath to set the tags root on the resource - /libs/settings/cq/search/facets/sites/jcr:content/items/tags
You can overlay and amend accordingly
