How to avoid multiple ngIf in Angular's template

I'd like to know what is the best way to avoid using multiple *ngIf in template. For example, in a component's template, depends on the route, i have to generate multiple different elements like that:

<div *ngIf="route == 'page1'">Title for page 1</div>
<div *ngIf="route == 'page2'">Title for page 2</div> 

<i *ngIf="route == 'page1'" class="fa fa-message"></i>
<i *ngIf="route == 'page2'" class="fa fa-bell-o"></i>

<div *ngIf="route == 'page1'">
    <button>...</button>
</div>
<div *ngIf="route == 'page2'">
    <div class="menu"></div>
</div>

It'll become messy soon, so i came up with a solution, in this component's ts file, i defined an array:

arr_1 = [
    { type: "text", content: "Title for page 1" },
    { type: "icon", class: "fa fa-message" },
    { type: "button", content: "..." }
]

arr_2 = [
    { type: "text", content: "Title for page 2" },
    { type: "icon", class: "fa fa-bell-o" },
    { type: "menu", menu_children: [...], class: "menu" }
]

In its template:

<div *ngIf="route == 'page1'">
    <generator *ngFor="let ele of arr_1"
        [type]="ele.type"
        [class]="ele.class"
        [content]="ele.content"
        [menu_children]="ele.menu_children"
    >
    </generator>
</div>

<div *ngIf="route == 'page2'">
    <generator *ngFor="let ele of arr_2"
        [type]="ele.type"
        [class]="ele.class"
        [content]="ele.content"
        [menu_children]="ele.menu_children"
    >
    </generator>
</div>

And i created a GeneratorComponent that receives the type and generate the corresponding element:

@Component({
     selector: 'generator',
     ...
})
export class GeneratorComponent {
    @Input() type: string;
    @Input() content: string;
    @Input() class: string;
    @Input() menu_children: string;
}

GeneratorComponent's template:

<div *ngIf="type == 'text'"></div>
<i *ngIf="type == 'text'"></i>
...

The problem here is the class GeneratorComponent will have multiple properties and they are not used for one reason (for example: content and menu_children have no relation).

Do you have any idea to fix my solution ? Other solutions will be appreciated.

Thanks !
