Custom Zone 
A custom zone is a scope slot that allows you to introduce custom content to a form.
Usage 
- Drag and drop the Custom field into the form canvas area. 
- Specify the data type (string, object, array) for the custom field. 

3.You can write you own code on custom zone in the GenerateForm generator.
vue
<fm-generate-form 
    :data="jsonData"
    ref="generateForm"
  >
  <template v-slot:blank="scope">
    <!-- custom zone -->
    <!-- use v-model="scope.model.blank" to bind data -->
    <el-input v-model="scope.model.blank" />
  </template>
</fm-generate-form>View the effect
表单数据: {}
TIP
In scope.model.blank, The blank is the custom field ID。
Binding Complex type 
When Custom fields bind data type to object (array).
vue
<fm-generate-form
    :data="jsonData"
    ref="generateForm"
  >
  <template v-slot:blank="scope">
    <!-- custom zone -->
    <!-- use v-model="scope.model.blank" to bind data -->
    Width:<el-input v-model="scope.model.blank.width" style="width: 100px"></el-input>
    Height:<el-input v-model="scope.model.blank.height" style="width: 100px"></el-input>
  </template>
</fm-generate-form>View the effect
Form Data:{}
Import Static Content 
Static content does not bind data, [Unbind Data](./data-bind.md#Unbind Data) can be found in the field Properties panel.
vue
<fm-generate-form 
    :data="jsonData"
    ref="generateForm"
  >
  <template v-slot:blank>
    <!-- custom zone -->
    This is a static piece of text
  </template>
</fm-generate-form>View the effect
