QGIS 3 Atlas: text box expression for automatically displaying names of all visible features?

Question

I am currently working with the QGIS (3.6) map composer using the atlas tool; it's quite handy, but I've come across a small problem and I'm wondering if there is a solution to this.

The coverage layer is a multi-polygon layer with different survey fields (see image)

I would like to add a text box to the map layout automatically displaying the name of the current feature (in the centre), as well as the names of the other visible features in the map layout. For example, the text could read "map showing the outlines of field_a, field_b, field_c etc."

I know that I can use the "expression"-function for obtaining the name of the current feature, but is there also an expression to obtain all of the other ones?

Answer 1

Add an attribute table to the layout.

In the item properties tab, choose the option to "show only features within a map."

Click the "Attributes" button to open a dialogue that lets you choose which columns to display - turn off all the columns except "Name". In this dialogue you can also edit the displayed column name.

This should give you a list of the Names of all the features in your chosen layer on the current map.

If you have multiple layers, add another table for each layer.
