How to pass variable to "data-target=" angular 2

To pass a variable in Angular 7 you can use it just like:

[attr.data-target] = "theme.themeId"

Yes exactly you can use

*ngFor="a of Array; index as i;"

and

[attr.data-target]="'#test' + i"

and

name="test{{i}}

You could used attribute binding. Something like that:

[attr.data-target]="'#' + theme.themeId"
