I'm building a webapp which main purpose is displaying widgets on a display. These widgets have an variable size, so not every widget is even high or wide (But they are using standards like for example a grid system). Now I'm looking for the best way to save which widgets are used, and where they are placed. For example by using something like Gridstack the user can drag and place the widgets in an admin panel, but how should I save this? And how can I recall this and put in a empty Bootstrap page for example. Working with the Bootstrap Grid system would be great aswell.
I did some research on Google and here but didn't find any plugins or ways to do this.
