How can I select all options of a multiple amp-selector?

I have an amp-selector with multiple options. I know that if I want to clear all the selections, I can bind <apm-selector-id>.clear on a tap event on a button.

Example:

<button on="tap:mySelector.clear">Clear Selection</button>

Is there a way I can do something similar in order to select all options? I have many options and I do not want to compel my user to click on each one of them, if they want to select them all. I just want them to click on a button and have all options selected, all together, with one click.

Solution

Currently there is no action registered that does what you are asking.

However, you can fork the repo on github, add the functionality and do a pull request. It's pretty simple and easy to do.

Another option you have is to start out with all options selected and have the user deselect the undesired ones.
