Draggable element must have an item slot
This error occurs when using the draggable
attribute without providing an item
slot for the draggable element. The draggable
attribute is used to make an HTML element draggable by the user.
Example:
Let’s say we have a list of items that we want to make draggable. Each item is represented by a `
` element with the class `item`. To make these items draggable, we can use the `draggable` attribute.
<div class="item" draggable="true">Item 1</div>
<div class="item" draggable="true">Item 2</div>
<div class="item" draggable="true">Item 3</div>
However, if we try to drag any of these items without specifying an `item` slot, we will encounter the “draggable element must have an item slot” error.
Solution:
To fix this error, we need to wrap the draggable elements inside a container element (e.g., a `
`) and provide an `item` slot for each draggable element using the `slot` attribute. The `slot` attribute is used to give a name to a slot inside a `` element, which can be used to represent dynamic content.
<div>
<template>
<div class="item" draggable="true" slot="item">Item 1</div>
<div class="item" draggable="true" slot="item">Item 2</div>
<div class="item" draggable="true" slot="item">Item 3</div>
</template>
</div>
Now, the draggable elements have the `item` slot defined, and we won’t encounter the error anymore.
