Hi, Im new to canvas and i was trying to know if it's possible to set a filter values of a map based in a value that i get from the urlparam function, like this:
```auto
var_set name="var" value={urlparam param="parameter" default="not_found"}
/*set the filter here*/
| savedMap id="..."
| render
```

That is not possible. Maps do not use expression language.
You can, however, store a filter with your map saved object. To do this, open the map and add query, filter, and time constraints. Save the map. Now anywhere this map is loaded, those query and filter constraints will be applied.
If you are looking to display a map along with other visualizations, I would recommend using [dashboard](https://www.elastic.co/guide/en/kibana/8.6/dashboard.html). Dashboard allows for passing filters to all panels.
