Back button

[kurch00]

I have 3 dashboard states. The first one contains a table that shows all customers. The second (clicking on a row) contains all devices from the selected customer. And the third contains general information about the selected device. How can I create a back button on the third dashboard state to the second dashboard state, but without losing the information, such as all devices from the previously selected customer?

That's true, i have a button which executes a history.back() but the update of the last state loses, it's quiet frustating, if anyone know how to keep the state despite the history.back() would be really useful!

Hi @nicovon24 and @kurch00 , you could follow the tips below to create a dedicated Thingsboard button :

1. Create a Markdown widget and add the device alias / info in the Data source
2. In the Appearance Tab of the Widget, activate Use Markdown/HTML value function and use this code as a base :

return '<div class="header" fxLayout="row" fxLayoutAlign="center center" fxLayoutGap="0px">' +

        
        '<div class="button" fxFlex fxLayout="row" fxLayoutAlign="center " style="padding-right: 0px;">' +

             '<button mat-raised-button color="primary" id="close">' +
              '<mat-icon>highlight_off</mat-icon>' +
              'close ' +
            '</button>'
        
        '</div>'
        +
'</div>';
        

Finally in the Action Tab of the Widget add an action "On HTML element Click" with "close" name and enable set entity from widget.

I hope it helps

Thank you!! I found another way to make it work too. The idea was to create a menu/header, so I created one and inside the HTML, I put a button with an ID. In the actions feature, I called it using "Update current dashboard state". However, it wasn't working yet. So, at the point where I wanted to go back, I disabled the "Set entity from widget" option, and it worked out!!

Perfect, @kurch00 happy that it works for you.
You can also inclue the code snippet I gave into your menu if you want :)
