Hey there! I’ve run into this exact issue before when using Vuetify in a partial page context—<v-app> is built to be the root container for full-screen apps, so its default styles force it to take up more space than needed when embedded in a small section of a page. Let’s walk through the fixes that should resolve this for you:

1. Ditch <v-app> entirely (recommended for partial use) #

Since you’re only using Vuetify in a small part of your page, you don’t actually need the full <v-app> wrapper. It comes with default styles like min-height: 100vh which is why it’s hogging that extra space. Replace it with a plain div or keep the <v-container> directly:

</div>
<div id="vuetify_edit">
  <v-container>
    <v-form>
      <v-jsf v-model="editModel" :schema="editSchema" />
    </v-form>
  </v-container>
</div>
<div>...

This lets your container shrink to fit the actual content of <v-jsf> without the forced full-screen constraints of <v-app>.

2. Override <v-app> styles if you must keep it #

If you need <v-app> for some component context (though this is rare for partial setups), you can override its default height rules with custom CSS:

#vuetify_edit {
  min-height: auto !important;
  height: fit-content !important;
  width: fit-content !important; /* Optional, if width is also an issue */
}

The fit-content value tells the element to only take up as much space as its content needs, and min-height: auto cancels out Vuetify’s default minimum height setting.

3. Tweak child components for tighter spacing #

You can also trim extra space from the child components to get that perfect fit:

• Add the fluid prop to <v-container> to remove its default max-width constraints
• Use Vuetify’s spacing classes like pa-0 (padding all 0) or ma-0 (margin all 0) to eliminate extra padding/margin:

  <v-container fluid class="pa-0 ma-0">
    <v-form class="pa-0">
      <v-jsf v-model="editModel" :schema="editSchema" />
    </v-form>
  </v-container>
  

Quick Note #

Vuetify’s layout components like <v-app>, <v-content>, and <v-navigation-drawer> are designed for full-page apps. When using Vuetify in a partial section of a page, sticking to individual UI components (like <v-form>, <v-input>, <v-jsf>) without the root layout wrappers will save you a lot of layout headaches.
