<script>
    export let params = {}

    let seasons = [];
    let selected = '';

    onMount(async () => {
        selected = params.seasonId; 
    /* fetch is called here and returns a list of seasons, which is passed to seasons array */
    })
</script>

<p><select bind:value={selected}>
    <option value="" disabled>-- Select Season --</option>
    {#each seasons as season}
    <option value={season.id}>{season.description}</option>
    {/each}
</select></p>
<p>param: {params.seasonId}</p>
<p>Selected: {selected}</p>

<p><select>
    <option value="" disabled>-- Select Season --</option>
    <option value="4">2019</option>
    <option value="3">2018</option>
    <option value="2">2017</option>
    <option value="1">2016</option>
</select></p>
