          label: 'Select Items',
          slot: 'page1',

        },
        {
          label: 'Apply',

        }
      ],
    };
  },
  methods: {
    nextClicked(currentPage) {
      console.log('next clicked', currentPage)
      return true; //return false if you want to prevent moving to next page
    },
    backClicked(currentPage) {
      console.log('back clicked', currentPage);
      return true; //return false if you want to prevent moving to previous page
    }
  },
};
</script>

This should result in the screenshot seen above

Component Options

Option Description Type, Example
steps (required) Array of objects that specify step titles and page id 
[
  {
    label: 'Add Constraints', // title for wizard step
    page: 'page2', //id for div to show for this step
  },
  //...
]
onNext (optional) function called before next page is shown. This is a good place to do validation etc. Return true to proceed, or false to stay on the same page. function ex: 
function(currentPage){
  console.log(currentPage);
  return true;
}
onBack (optional) function called before previous page is shown. Return true to proceed, or false to stay on the same page. function ex: 
function(currentPage){
  console.log(currentPage);
  return true;
}
Label options
previousStepLabel label for previous step default: 'Back'
nextStepLabel label for next step default: 'Next'
finalStepLabel label for final step default: 'Save'

Advanced usecase - Call next or back asynchronously

In some cases, you might want to change step programmatically. The most common usecase for this is if you want to call an asynchronous action on next/back click and then in the callback want to either go to the next step or stay on the same step.

Following is an example of how this can be done using vue-good-wizard

<template>
  <div>
    <vue-good-wizard 
      ref="wizard"
      :steps="steps"
      :onNext="nextClicked" 
      :onBack="backClicked">
      <div slot="page1">
        <h4>Step 1</h4>
        <p>This is step 1</p>
      </div>
      <div slot="page2">
        <h4>Step 2</h4>
        <!-- lets say, this is where my form is that needs to be validated -->
        <el-form :model="myForm" ref="myForm">
        </el-form>
      </div>
      <div slot="page3">
        <h4>Step 3</h4>
        <p>This is step 3</p>
      </div>
    </vue-good-wizard>
  </div>
</template>

<script>
export default {
  name: 'demo',
  data(){
    return {
      steps: [
        {
          label: 'Select Items',
          slot: 'page1',
        },
        {
          label: 'My form',
          slot: 'page2',
        },
        {
          label: 'Review',
          slot: 'page3',
        },
      ],
    };
  },
  methods: {
    nextClicked(currentPage) {
      const _this = this;

      // if we're on the form page
      if (currentPage == 1) {

        // on next, we need to validate the form
        _this.$refs.myForm.validate((valid) => {
          if (valid) {

            //all is good, lets proceed to next step
            _this.$refs.wizard.goNext(true);
          } else {

            //error. don't proceed.
            console.log('error submit!!');
            return false;
          }
        });
        return false; //don't proceed by default. 
      }
      return true; //return false if you want to prevent moving to next page
    },
    backClicked(currentPage) {
      console.log('back clicked', currentPage);
      return true; //return false if you want to prevent moving to previous page
    }
  },
};
</script>
