Persist dashboard panel expand/collapse state in URL

[ytzlax]

All actions in kibana dashboard change the URL, actions like filtering, open and close legend and etc..
But expand and collapse visualisation to full screen, doesn't change the URL.
I think that click on expand visualisation need to change the URL like other actions.

Can you explain a bit more about your use case and why this feature would be important to you?

We have so much state already stored in the URL that it's become very long and unwieldy, in addition to causing issues with hitting max url length limits. We've been trying to only store important variables in there, and it was consciously decided that the panel expand/collapse state was not important enough to require persisting across url sharing. That it was more of a temporary exploration state. If you can give us some more context, we can reconsider this decision.

Hi,
In my company we developed application, inside the application I embed iframe kibana dashboard,
in each visualization left side I placed a button(outside of the iframe), when the user click on expand kibana button, all my application buttons need to disappear.
My problem is how can I know when the user click on the expand button.
If its problem to store the state in the URL, maybe you can fire event that the expand button clicked,
thats what I did inside kibana code I added
$rootScope.$emit('$toogleExpand');
in file %KIBANA_HOME%\src\core_plugins\kibana\public\dashboard\dashboard.js

$scope.toggleExpandPanel = (panelIndex) => {  
        $rootScope.$emit('$toogleExpand');

        if ($scope.expandedPanel && $scope.expandedPanel.panelIndex === panelIndex) {
          $scope.expandedPanel = null;
        } else {
          $scope.expandedPanel =
            dashboardState.getPanels().find((panel) => panel.panelIndex === panelIndex);
        }
      };

thanks

Not if this is related to #2716, but having legend state persisted (ie when I save a dashboard with some legends closed they should stay that way on a reload/refresh) would be super handy.

Closing this in favor of #145454.

We have recently removed almost all dashboard state from the URL, but maximized panel state is considered more of a location than an internal dashboard state, so we've decided to expose it. Check the linked issue for tracking.
