[Qgis-user] Applying multiple styles to the same layer

[Karl Magnus Jönsson]

Hi,
Another option is to add named styles to the layer and switch between them. And if you want, associate them with map themes for quick switching.

Hi Patrick,

I don't think that duplicating a layer is such a big problem. I only advice you to avoid editing the two layers at the same time.

Another option is to use rule-based symbology, which allows you to set a rule (filter) for when the feature are drawn. If you create non exclusive filter, a feature can be drawn several times.

Hope it helps,

Good day to all.

I have a Qgis project in which I would like to be able to have the same
layer appear twice in the layer list so that I can apply different
styling to it in each instance.

At the moment I am not aware of how I might do this apart from adding
the same layer to my project twice.

The layers are local Geopackage files (.gpkg) and there is known the
issue that Sqlite documentation does recommend against multiple
connections to a dataset, especially over a network, as this is somewhat
outside the design expectations of Sqlite.

Is there any other way I can have two different styles applied to a layer?

TIA
