Svelte – Select Multiple

---

Alright guysss..welcome back to Svelte channel.. hahah bukan yahhh.. welcome back to our channel… Okay kita lanjut ya untuk post lagi materi svelte..

Pertama kita buat file SelectMultiple.svelte

<script>
	let scoops = 1;
	let flavours = ['Mint choc chip'];

	let menu = [
		'Cookies and cream',
		'Mint choc chip',
		'Raspberry ripple'
	];

	function join(flavours) {
		if (flavours.length === 1) return flavours[0];
		return `${flavours.slice(0, -1).join(', ')} and ${flavours[flavours.length - 1]}`;
	}
</script>

<h2>Size</h2>

<label>
	<input type=radio bind:group={scoops} value={1}>
	One scoop
</label>

<label>
	<input type=radio bind:group={scoops} value={2}>
	Two scoops
</label>

<label>
	<input type=radio bind:group={scoops} value={3}>
	Three scoops
</label>

<h2>Flavours</h2>

<select multiple bind:value={flavours}>
	{#each menu as flavour}
		<option value={flavour}>
			{flavour}
		</option>
	{/each}
</select>

{#if flavours.length === 0}
	<p>Please select at least one flavour</p>
{:else if flavours.length > scoops}
	<p>Can't order more flavours than scoops!</p>
{:else}
	<p>
		You ordered {scoops} {scoops === 1 ? 'scoop' : 'scoops'}
		of {join(flavours)}
	</p>
{/if}

dan kemudian kita import ke App.svelte kita sehinnga menjadi :

<main>
	<h1>Hello {name}!</h1>
	<p>Visit the <a href="https://svelte.dev/tutorial">Svelte tutorial</a> to learn how to build Svelte apps.</p>
	<Counter />
	<Toggle />
	<Img />
	<String />
	<Statement />
	<Condition />
	<Nested answer={42}/>
	<Nested/>
	<Info {...pkg}/>
	<IfLogin />
	<Comparison />
	<EachYoutube />
	<KeyEachThing />
	<GenerateNumber />
	<MouseMove />
	<MouseMoveInlineHandler />
	<EventModifier />
	<AlertCompEvent />
	<AlertEventForwarding />
	<CustomButtonComp />
	<TextInput />
	<NumericInput />
	<CheckboxInputs />
	<GroupInputs />
	<TextareaInputs />
	<FileInput />
	<SelectBindings />
	<SelectMultiple />

</main>

dan hasilnya :
