How do I hide the map details?

If you open this: Network

The map details open, but they block all the relevan information. How do I stop the map details from popping up?

I assume you control the HTML of this page.

The parameters for the iframe that embeds the link to umap.openstreetmap.fr have a lot of options that can be switched on or off - you would need to experiment with them to find what works best. They can be found in the “Embed and link options” in the “Share and download” panel (see screenshot).

I believe the one you are mainly looking for is “Do you want to display a panel on load?” which affects the onLoadPanel setting in the iframe code.
