I want to create a onetime button that could store it's state.
The button state should be a part of form$.requestData.
What is the best way to create it?

Try to take a slightly different approach. Let's get rid of defineElement altogether which wouldn't be necessary anyway as we're defining an element with composables from ground up. Let's also use non-static exports of the composables (as our element is no longer considered static because it has data) and add useNullValue.

Here's what you should get:

<template>
  <ElementLayout ref="container">
    <template #element>
      <!-- Use `button` tag -->
      <template v-if="buttonType === 'button'">
        <!-- Use it as HTML -->
        <button
          v-bind="{
            ...button,
            ...aria,
          }"
          v-html="buttonLabel"
          :tabindex="isDisabled || isLo…

Option 1 - Create a new element

You can create a new Vueform element first based on this guide:
https://vueform.com/docs/creating-elements

New elements always have a model by default. You can add a template and features based on the ButtonElement:
https://github.com/vueform/vueform/blob/main/themes/blank/templates/elements/ButtonElement.vue
https://github.com/vueform/vueform/blob/main/src/components/elements/ButtonElement.js

Then you could add it as a Builder element:
https://builder.vueform.com/docs/custom-elements#creating-new-elements-with-custom-configuration-panel

Option 2 - Create a plugin and custom template for `ButtonElement`

You can override the template for ButtonElement:
https://vueform.com/docs/styles-and-layout#replacing-templates

Or create an alternative view:
https://vueform.com/docs/styles-and-layout#alternative-views

Then use a plugin to add a model:
https://vueform.com/docs/plugins

If you need help with any specific aspect, let me know.

Thanks @adamberecz for response!

I've created a new element based on ButtonElement, but I have some problems:

deleting element in Builder causes isStatic reading error
value is saving in form.data but it does'n set back on form load, I see false and only clicking change it becomes true. And it comes false on the form reload. (other values set back ok, except custom elements)

My custom Button:

<template>
  <ElementLayout>
    <template #element>
      <button-element v-if="!isDisabled && !isReadonly"
                      v-bind="$props"
                      @click="onClickHandler"
      >
        {{ buttonLabel || 'Save' }}
      </button-element>
    </template>
  </ElementLayout>
</template>

@adamberecz I hope you just missed my answer.
Any comments here?
Is it a bug or I do something wrong?

You were close. Using the template of the original ButtonElement (with some simplification) is the recommended approach here, as you would get basically an identical button element that you can further customize:

<template>
  <ElementLayout ref="container">
    <template #element>
      <!-- Use `button` tag -->
      <template v-if="buttonType === 'button'">
        <!-- Use it as HTML -->
        <button
          v-bind="{
            ...button,
            ...aria,
          }"
          v-html="buttonLabel"
          :tabindex="isDisabled || isLoading ? -1 : undefined"
          :class="classes.button"
          :disabled="isDisabled"
          @click.prevent="onClickHandler" 
        ></button>
      </template>

    </template>

    <!-- Default element slots -->
    <template v-for="(component, slot) in elementSlots" #[slot]><slot :name="slot" :el$="el$"><component :is="component" :el$="el$"/></slot></template>
  </ElementLayout>

I managed to add/remove this in the builder without error.

@adamberecz, I tried your solution and I need your kind assistance with the following findings:

Builder errrors

If I create this button in empty form it's ok, but when I create it in a container, clone it and delete it then I get console errors:

Also I get the same on moving outside a container/list

Form data

When I test it builder preview, then the data appeared only by clicking the button placed in list/nested list.
But no value is set to form data when the button is placed in a container or in the form root(empty form).

Form loading

The stored data still isn'l loaded on form$.load(data), I execute it on the main form.
Is any way to load data directly to the component to test this? By the way it could the form loading bug.

      this.update(true);
      this.$emit('click');
      console.log('SaveContainerButtonElement onClick', this.value);
    }
  },
};
</script>

Testing it the mentioned scenarios did work for me without errors.
