Organize layers

Arrange the layers in a map's legend, and group related layers so people can switch between them with a slider or dropdown.

In edit mode, use the legend to delete, reorder, rename, and group layers. The List tab shows every layer and group. To open it, click Edit map in the toolbar at the top right of the map, then click List at the top of the legend or press 2.

Delete a layer

Deleting a layer removes it and its data from this map only.

1. In edit mode, click the layer's ··· menu in the legend.

2. Click Delete.

To delete several layers, Cmd-click (Mac) or Ctrl-click (Windows) each one, then press Delete.

To bring back a deleted layer, press Cmd+Z (Mac) or Ctrl+Z (Windows) before you close the map. See Save and undo changes.

Change the layer order

In edit mode, drag a layer up or down in the Legend or List tab. To move a layer into or out of a group, or to reorder the layers inside a group, drag it in the List tab.

On the map, Felt draws annotations on top, then point layers, line layers, and finally polygon and raster layers. Within each geometry type, layers stack in list order.

Rename a layer

1. In edit mode, select the layer in the legend.

2. Click the layer's name at the top of the detail panel.

3. Enter the new name and press Enter.

To rename a column instead, see Edit features.

Layer groups

A layer group puts related layers, such as a survey's yearly layers, under one name in the legend. People can turn the whole group on or off at once. Uploading an Excel file with several sheets, or a ZIP file with several Shapefiles, creates a group automatically.

Create a layer group

1. In the List tab, Cmd-click (Mac) or Ctrl-click (Windows) the layers you want to group.

2. Press Cmd+G (Mac) or Ctrl+G (Windows), or right-click a selected layer and click Group > Group selection.

3. Enter a name for the group.

To add a layer to a group later, drag it into the group. To take it out, drag it out of the group, or right-click it and click Group > Remove from group. A group can't contain another group; use several groups instead.

Group types

Available on the Business and Enterprise plans. Compare plans

A group's type sets how people viewing the map switch between its layers. In edit mode, select the group, then select a Type in the Legend section of the detail panel. Every type except List needs at least two of the group's layers shown in the legend.

Type	What people viewing the map see	Good for
List	Each layer with its own show and hide control	Layers people may want to combine
Slider	A slider that moves through the layers one at a time, in list order	Time steps, such as one layer per year
Single-select	A dropdown to pick one layer at a time	Alternatives, such as different scenarios
Multi-select	A dropdown to pick any number of layers	A long set of optional layers

Layer sliders

A layer slider is a Slider group of vector or raster layers. The slider follows list order, so for a time series, arrange the layers from oldest to newest.
