@giswqs Thank you for the video above and updating Leafmap.

I have since updated my Leafmap version, and retried adding a shapefile, using the same method as the video above, however, the preset column heading are still not populating?

Here is a test shapefile made and exported from QGIS containing three column headings:

Here is the video of adding the same exported shapefile to Leafmap and no Keys automatically populate?

I am using Leafmap 0.10.5 and ipyleaflet 0.17.0 as I needed to downgrad ipyleaflet for use of the measure tool.

Thank you for your support and guidance.

You need leafmap v.0.16.0 for this feature.

[PennyJClarke]

Thank you.

I used conda install -c conda-forge leafmap and conda install leafmap=0.16.0, using both only offers Leafmap 0.15.0:

I removed Leafmap before reinstalling and also tried updating the package, and in both cases 0.15.0 was the newest version offered?

[giswqs]

Create a fresh conda env to install leafmap. There might be some Python packages in your existing env that prevent leafmap from being installed.

@giswqs thank you for all your support to add this new feature, it is great! I successfully downloaded the new version of Leafmap and the feature works. I see by amending os.environ['MAX_PROPS'] = '20' I can increase the number of rows in the grid, however, beyond 21 I cannot see any additional rows on the screen, even in full screen view. Is it possible to scroll the rows or add a scroll feature to the attribute table? Thank you for your time.
