I have an astro component and I want to wrap it with another <div> element, but only if some property is set.
#Component - if prop then wrap

Hi @snow sleet. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
In Astro, you can conditionally render HTML elements based on the value of a prop. Here's an example of how you can achieve this:
---
const { wrap, ...props } = Astro.props;
---
{wrap && <div class="wrapper">}
<YourComponent {...props} />
{wrap && </div>}
In this example, the YourComponent will be wrapped with a <div> element if the wrap prop is set to a truthy value. If wrap is falsy or not provided, the YourComponent will not be wrapped.
Remember to replace YourComponent with the actual component you want to conditionally wrap.
For more information on conditional rendering and using props in Astro, you can refer to these resources:

Let me check the knowledge base for you. One moment! :books:
I apologize for the confusion. The correct syntax for conditional rendering in Astro is a bit different. Here's how you can conditionally wrap a component based on a prop:
---
const { wrap, ...props } = Astro.props;
---
{wrap ? (
<div class="wrapper">
<YourComponent {...props} />
</div>
) : (
<YourComponent {...props} />
)}
In this example, if the wrap prop is truthy, YourComponent will be wrapped with a <div> element. If wrap is falsy or not provided, YourComponent will not be wrapped.
Remember to replace YourComponent with the actual component you want to conditionally wrap.

@vague radish was hoping to avoid writing double the component code

I understand your concern. To avoid duplicating the component code, you can use a combination of JavaScript and Astro's slot feature. Here's how you can do it:
---
const { wrap } = Astro.props;
---
<div class={wrap ? 'wrapper' : ''}>
<slot />
</div>
In this example, you create a wrapper component that accepts a wrap prop. If wrap is truthy, the wrapper will have a class of 'wrapper'. You can then use this wrapper component to conditionally wrap any other component:
<Wrapper wrap={someCondition}>
<YourComponent />
</Wrapper>
In this case, YourComponent will be wrapped with a <div> with the class 'wrapper' if someCondition is truthy. If someCondition is falsy, YourComponent will still be wrapped with a <div>, but without the 'wrapper' class. You can style your CSS accordingly to make the wrapper invisible when the 'wrapper' class is not present.
