I've been trying to wrap my head around the vue virtual scroller. I couldn't help but notice in the demo that it utilizes a few HTML attributes...
<virtual-scroller v-if="scopedSlots" class="scroller" :item-height="itemHeight" :items="items" main-tag="section" content-tag="table" :buffer="buffer" :pool-size="poolSize">link to the specific line on source code
Where does this functionality originate from and where can I find more information about it?
In the file ../src/components/VirtualScroller.vue, you will find the declaration of props.
Both "content-tag" and "main-tag" are props of type String, which means you can specify any HTML elements that you prefer. In the provided example, "section" and "table" are passed to each prop as strings. If no value is provided, it will default to "div" as defined here: https://github.com/Akryum/vue-virtual-scroller/blob/master/src/components/VirtualScroller.vue
You can also dynamically pass a string by using :item-height="itemHeight", where you would have either :main-tag="mainTag" or :main-tag="anyCustomMainTag". This allows you to set mainTag or anyCustomMainTag to your desired string value, overriding the default div.
Explanation:
v-if - a Vue directiveclass - standard HTML attribute that is commonly used.item-height- a computed method.items - a property of the data object.buffer - another property of the data objectpool-size - also a property of the data objectPlease note that while item-height is written in kebab-case in HTML, it should be camelCase in JavaScript, like this: itemHeight
Regarding the content-tag and main-tag - it would be best to inquire with the developer on GitHub. These elements are not part of the official Vue API or HTML specifications.
