Topic: How to user mdb-stepper with custom objects list ?
Expected behavior I'm trying to display a mdb-stepper with custom length depending of custom objects list size.
Actual behavior Error : "this.$refs.stepContent is undefined"
Resources (screenshots, code snippets etc.) I'm trying to do this :
<mdb-stepper simpleV :steps="objects.length" buttons validation>
<div v-bind:key="index" v-for="(object, index) in objects">
<template>...</template>
</div>
</mdb-stepper>
How to do this please ? Thanks a lot
Each step needs to be represented with its own template - so this is the element you have to use v-for on - although it cannot be keyed, so in the example below we are binding the key value to the div inside:
<mdb-stepper simpleV :steps="objects.length" buttons>
<template v-for="(object, index) in objects" #[index+1]>
<div :key="index">{{ object.name }}</div>
</template>
</mdb-stepper>
Best regards, Magdalena
I still have two problems with this mdb-stepper :
- Error displaying when trying to make this stepper with validation :
Error in mounted hook: "TypeError: this.$refs.stepContent is undefined"
I'm using this code :
validate(step) {
this.$refs[`vertical${step}`].classList.add("was-validated");
if (step === 1 && this.name.length > 0)
this.validatedSteps[1] = true;
else if (step === 2 && this.surname.length > 0)
this.validatedSteps[2] = true;
},
submit() {
console.log(`${this.name} has submitted the form.s`);
}
- First item not showing properly (see screenshot) :
Could you please help me ? thks a lot

The problem is actually caused by the data being fetched later - stepper needs to get the step's height in the mounted hook. We didn't anticipate dynamic usage of this component - I'm adding this to our task list. I suspect that the second issue is caused by wrongly calculated height in the mounted hook. We'll include the fix in the upcoming release. Kind regards, Magdalena
