I have formulated a map in an HTML file and use the standard frame widget to display it. The file is in the “HTML” directory and it works quite well so far.
Now I would like to display information from number and contact items in the same widget. Unfortunately that doesn’t work so far. Is it even possible and can someone help me?
Well you can basically do anythingiin an HTMLoof an webview. But this is then not concerned to OH except if you would use the REST API to set or get something.
Moreoveryyour explanation is very short, so this is the only answer to give: yes you can basically do anything within the webview, even use some well known framework such as vuejs to accelerate and easy more complex tasks
