I'm trying to create the following:
I receive an array of objects. Each object consists of an id, an option, and a group name. I need to output the data in a way that firstly I have a checkbox with a value of a group name property and then a list of checkboxes which have the same group properties. For instance, let's say I recieve the following data:
[
{id:1, text: 'Football', group: 'sport'}
{id:2, text: 'Basketball', group: 'sport'}
{id:3, text: 'Cookie', group: 'food'}
{id:4, text: 'Soup', group: 'food'}
]
So the output should be the following:
<checkbox which when clicked should select all checkboxes belonging to this group>Sport</checkbox>
<checkbox>Football</checkbox>
<checkbox>Basketball</checkbox>
<checkbox which when clicked should select all checkboxes belonging to this group>Food</checkbox>
<checkbox>Cookie</checkbox>
<checkbox>Soup</checkbox>
So far I have the following:
export default { data() { return { actionTypes: actionTypes, relationTypes: relationTypes, optionsList: [ {id:1, text: 'Football', group: 'sport'} {id:2, text: 'Basketball', group: 'sport'} {id:3, text: 'Cookie', group: 'food'} {id:4, text: 'Soup', group: 'food'} ] optionsGroupsList: ['Sport', 'Food'], localValue: [] },
<link href="https://cdn.jsdelivr.net/npm/vuesax/dist/vuesax.css" rel="stylesheet"/> <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script> <div v-for="group in optionsGroupsList" class="checkbox-group"> <vs-checkbox :vs-value="group" :key="group" > {{ group }} </vs-checkbox> <vs-checkbox v-for="option in optionsList" v-if="option.group === group" :vs-value="option.id" :key="option.id" v-model="localValue" > {{ option.text }} </vs-checkbox> </div>
So I do receive the necessary output but I have no idea how to make the group checkboxes work in a way that they select the checkboxes belonging to them (to this group)
I would really appreciate any ideas, thanks in advance!
nestedOptions: [
{
name: "sport",
options: [
{ id: 1, text: "Football", group: "sport" },
{ id: 2, text: "Basketball", group: "sport" },
]
},
{
name:"food"
options: [...]
}
]
export default {
name: "groupedOptionsComponent",
data() {
return {
selectedOptions: [],
selectedGroups: [],
optionsList: [
{ id: 1, text: "Football", group: "sport" },
{ id: 2, text: "Basketball", group: "sport" },
{ id: 3, text: "Cookie", group: "food" },
{ id: 4, text: "Soup", group: "food" }
],
optionsGroupsList: ["sport", "food"]
};
},
computed: {
nestedOptions() {
return this.optionsGroupsList.map(groupName => ({
name: groupName,
options: this.optionsList.filter(({ group }) => group === groupName)
}));
}
},
watch: {
selectedGroups: function(groups) {
this.optionsList.forEach(option => {
if (
groups.includes(option.group) &&
!this.selectedOptions.includes(option.id)
) {
this.selectedOptions.push(option.id);
} else {
this.selectedOptions = this.optionsList
.filter(({ group }) => groups.includes(group))
.map(({ id }) => id);
}
});
}
}
};
Makes your Template look something like this:
<template>
<div>
<div v-for="(group, index) in nestedOptions" class="checkbox-group" :key="index">
<vs-checkbox :vs-value="group.name" v-model="selectedGroups">{{ group.name }}</vs-checkbox>
<vs-checkbox
v-for="option in group.options"
:vs-value="option.id"
:key="option.id"
v-model="selectedOptions"
>{{ option.text }}</vs-checkbox>
</div>
</div>
</template>
