What is the best way to connect a boolean to the presence of an attribute in Angular 2?

Can a boolean variable be linked to the presence of an attribute?

 template: ...,
 host: {
   "[attr.disabled]": "disabled"
 }

When rendered in the element, this results in disabled="true" or disabled="false". However, I am looking for a way to utilize it in CSS using the [disabled] selector. I want the attribute to only exist if the variable is true, and not exist if it's false. Thank you in advance.

Answer №1

To remove a boolean attribute, the value must be set to null instead of false

"[attr.enabled]": "enabled ? false : null"
