Apply a directive conditionally

Question

I am using Material 2 to add md-raised-button. I want to apply this directive only if certain condition becomes true.

For example:

<         


        

Answer 1

This could be a solution too:

[md-raised-button]="condition ? 'true' : ''"

It's working for angular 4, ionic 3 like this:

[color]="condition ? 'primary' : ''" where condition is a function that decides if this is an active page or not. The whole code look like this:

{{ page.title }}
