Hi, In the future, we would appreciate if you could separate whose questions into topics - some of those answers might help other users as well but they're not so easy to find when unrelated questions are being asked together. 1) I think the best way to position elements in the row would be to use a grid and wrap checkboxes in mdb-col elements - this way you can control break-points as well. It's hard to tell without a code snippet where lays a problem, but the solution below should work as well:

 <div class="form-inline">
          <mdb-input
            type="checkbox"
            id="checkboxArray1"
            v-model="checkArray"
            checkboxValue="Jack"
            label="Jack"
            class="mb-2 pl-0"
          />
          <mdb-input
            type="checkbox"
            id="checkboxArray2"
            v-model="checkArray"
            checkboxValue="John"
            label="John"
            class="mb-2 pl-0"
          />
          <mdb-input
            type="checkbox"
            id="checkboxArray3"
            v-model="checkArray"
            checkboxValue="Mike"
            label="Mike"
            class="mb-2 pl-0"
          />
        </div>

2) That's not one of the default MDB options - I suppose you should inspect elements in the dev tools and change styling. 3). You can pass an empty string to remove a label

<mdb-switch onLabel="" offLabel="OFF"></mdb-switch>

4) It's impossible to tell where is the problem without a code snippet. Please create a separate topic and provide a code

5, 6) Unfortunately we don't have such options

7) DD-MM-YYYY, but Date Picker doesn't have format prop - you need to pass options object with this field

Kind regards, Magdalena
