Hi Yeongeun Seo, 

Have you checked the demo of this component which you can download from forge.

Update:

As per demo you need to put the loader inside the Interaction\Animate block, Please find working demo in attached oml. 

Cheers

Hi @Yeongeun Seo, 

If you are looking to implement Loader without a Component This link might help.

Thanks,
Vignesh Prakash.

The reason why you don't see the loader there is a bug in this component :  "OnParametersChanged" is not getting fired inside the LoaderSpinner and hence the style is not applied.

However if you place this component inside a gallery as per the demo you can see it working ( there it is working as OnParameter is fired ). You may look for alternative as @Vignesh Prakash suggested. 

This does not answer your question directly as it is specifically about this forge item, but if a spinner is what you're looking for, OutSystems provides you with these functionalities built-in. You do not need the forge for this.

Here I will give you two ways of doing this:

• Via OutSystem's default UI style template
• Via OutSystem's 'Animate' widget

Via OutSystem's default UI style template

Simply add a container to your screen and give it the style class "list-updating":

This will add the following spinner to your screen:

Add logic to the container or via an 'If' widget to determine when this container should be visible.

Via OutSystem's 'Animate' widget

You can also use the 'Animate' widget which comes with OutSystems itself as well:

Within this widget you can then place your own icon, photo or whatever and basically achieve the same result. If this widget is not showing up by default, you may need to add the dependency from the OutSystems UI module.

Hope this helps.
