Why is it so hard to apply interactive filters in AGOL?
It would be great additional feature to have a filter support expressions like TREE IN ('Maples', 'Pines'). Being able to select multiple values and filter on them.
For now you could create a nested filter that contains with the ANY option so in case any of the two filters is true, it should return the features (see example below, both point to the same layer and the result is that the two states are returned).
To explain a little more of what is needed to do this, here some additional explanation. In WAB select the filter widget:
Then Add a New Filter, select the layer (in mi case "Accidentes_QA") and give the filter a title (in my case "Filter accidents"). Very important is to add a set (of filter expressions):
The filter expression will look like this:
- Not that at the top "Any" is selected (so any of the expressions that test true will yield its results, comparable with using OR)
- Select the field (i my case "GRAVEDAD (String)")
- Select that a list of Unique values is presented}
- Switch the option "Ask for values" on
- Define the prompt (what the user will see): "Severity is" would be for instance select tree species or something similar
- Select the option "All unique values of this field"
- The second field will be the same field (in my case again GRAVEDAD (String)).
- Unique values
- Ask for values
- define the second prompt (add "or" in front of it)
- select again "All unique values of this field"
When you use the filter you will see this as initial state:
You can use a single value:
Or specify both values:
Gottcha! The only thing I am not seeing is the Prompt. In the example below I have "Business Sector is" yet no prompt is seen in the widget?
