You should be able to adjust it in your components style:

<style>
.q-layout-header {height: 1px}
// OR
.q-layout {height: 1px}
</style>

The screenshot did not post, so not sure if this fully answers your question, but hopefully it 's a start…

I have a dialog/modal that primarily needs the options, but I would like to add a small prompt/note to the selected options without having to write a custom modal. Any way to find a simple way to tag on a prompt as was previously possible with Dialog? Currently it appears that if you add a prompt after the options object, it only recognized the prompt and passes that through as data. Here’s the code I’m working with:

this.$q.dialog({
          title: 'Visit Result',
          color: 'primary',
          ok: true,
          cancel: true,
          options: {
            type: 'radio',
            model: 'opt1',
            inline: true,
            items: [{
              label: 'Not Home',
              value: 'Visited - Not Home',
              color: 'primary'
            },
            {
              label: 'Home',
              value: 'Visited - Home',
              color: 'primary'
            },
            {
              label: 'No Soliciting',
              value: 'Visited - No Soliciting',
              color: 'primary'
            },
            {
              label: 'Presented Fiber Service',
              value: 'Presented Fiber Service',
              color: 'primary'
            },
            {
              label: 'Ordering',
              value: 'Ordering',
              color: 'primary'
            },
            {
              label: 'Not interested',
              value: 'Not interested',
              color: 'primary'
            },
            {
              label: 'Stop back',
              value: 'Stop back',
              color: 'primary'
            },
            {
              label: 'Presented TDM Service',
              value: 'Presented TDM Service',
              color: 'primary'
            },
            {
              label: 'No Computer',
              value: 'No Computer',
              color: 'primary'
            }
            ]
          },
          prompt: {
            type: 'text',
            label: 'Add Visit Note',
            model: ''
          }
        })
          .then(data => {
            this.$q.notify({ message: `You chose ${JSON.stringify(data)}`, color: 'positive' })
          })
          .catch(() => {
            this.$q.notify({ message: 'Cancelled', color: 'negative' })
          })
