Slots

vue-jpql-autocomplete uses another vue package vue-autosuggest for providing the search box and options. Hence many features of this component can be used as is. The most important one being the slots for providing custom content within different sections of the control. The most common ones are:

<template slot="before-input"> content before the <input /> goes here </template>
<template slot="after-input"> content after the <input /> goes here </template>
<template slot="before-suggestions"> content before the <ul> goes here </template>
<template slot="after-section"> Default footer content for all sections </template>
<template slot="after-suggestions"> content after the <ul> goes here </template>
<template slot-scope="{suggestion}">Content for each suggestion as {{suggestion.item}}</template>

For complete details on how to use slots refer here.
Using scoped slots, one can easily change the displayed options of the suggestions.
