Did you mean on loading of buttons? If so, remove the loader property on q-btn (if it exists, because it is required in 0.14.9) and add a loading property bound on a data variable like this:

<q-btn @click="btnLoading = !btnLoading" :loading="btnLoading"> LOAD <q-spinner-hourglass slot="loading"/> </q-btn> ... data () { return () { btnLoading: false } }
