Showing filter options on embedded map of Carto?

Question

With Cartodb, is it possible to show the filter options on the embedded map?

The explain, I have generated a visualisation and have shared, but I want people accessing the visualisation to be able to filter the results.

The most common way to do this is by using CartoDB.js, the JavaScript library to build your own application. This lesson shows how to do it.

If you don't want to do JavaScript, you can create a multilayer map with each each layer being from the same original data table but with a different query applied to each. I made this map, by starting with one dataset and then clicking "add layer" and selecting the same dataset again. Once there are two layers, I applied different SQL to them. For example, something like this:

1st one: SELECT * FROM table_name WHERE var > 10

2nd one: SELECT * FROM table_name WHERE var <= 10

After that, you can turn on "layer selector":

Finally, you can toggle the layers in the upper right once the layer selector is toggled on:
