How to make a html search datalist for Vue

What do I mean by search suggestions

An example where I have use a datalist is on the search page. Another axample of this in action would look like this:

Adding the datalist to an input

To add a datalist to a text input you will need to add list="id" to your text input. For this, to work the list attribute needs to be set to the id of the datalist element.

<input type="search" placeholder="Search" list="data" />

Creating the datalist element

The datalist element is like the select element.

<datalist id="data">
	<option value="HTML" />
	<option value="CSS" />
	<option value="JavaScript" />
</datalist>

Implementing Vue

let us say you have a search form component using the above datalist and search input.

<form>
	<input type="search" placeholder="Search" list="data" />

	<datalist id="data">
		<option value="HTML" />
		<option value="CSS" />
		<option value="JavaScript" />
	</datalist>
</form>

Let's say that you have an array of search values that you would like to display in this datalist, for example, this array:

export default {
	data() {
		return {
			list: ["HTML", "CSS", "JavaScript"]
		};
	}
};
<form>
	<input type="search" placeholder="Search" list="data" />

	<datalist id="data">
		<option v-for="item in list" :key="item" :value="item" />
	</datalist>
</form>

Adding Gridsome

So you are using Gridsome (like me). Let's say that you would like your posts titles to show in this data list, You will need a page-query and use that instead of the data array.

<page-query>
query Search {
  allPost {
    edges {
      node {
        title
      }
    }
  }
}
</page-query>

Now for the new datalist.

<form>
	<input type="search" placeholder="Search" list="data" />

	<datalist id="data">
		<option v-for="{ item } in $page.allPost.edges" :key="node.title" :value="node.title" />
	</datalist>
</form>
