Since the tabbed pages code in the UI does not show the config section I added the hide configs directly to the jsondb storage (while openhab was stopped) in /var/lib/openhab/jsondb/uicomponents_ui_page.json to remove the bars:
"value": {
"uid": "page_a5c30b551f",
"tags": [],
"props": {
"parameters": [],
"parameterGroups": []
},
"timestamp": "Mar 16, 2023, 6:35:52 AM",
"component": "oh-tabs-page",
"config": {
"label": "test",
"sidebar": true,
"hideNavbar": true,
"hideSidebarIcon": true
},
