How to select checkboxes (vanilla html) on iPad using "next"?

The code

This is my vanilla html, nothing unusual, just a form, then some content, and then another form:

<form>

    <legend>Form #1</legend>

    <fieldset>

        <p>
            <label for="myInput">Tap in the box &gt;&gt;</label>
            <input type="text" id="myInput" />
        </p>

        <p>
            <label for="mySelect">Boselecta</label>
            <select id="mySelect">
                <option value="" selected="selected">Please select something...</option>
                <option value="proper">Proper</option>
                <option value="bo">Bo</option>
                <option value="i">I</option>
                <option value="tell">Tell</option>
                <option value="thee">Thee</option>
            </select>
        </p>

        <p>
            <label for="myCheckbox"> 
                <input type="text" id="myCheckbox" /> Check yoself before you wreck yoself      
            </label>    
        </p>

    </fieldset>

    <p>
        <input type="submit" value="Submit" />
    </p>


</form>

<form>

    <legend>Form #2</legend>

    <fieldset>

    <p>
        <label for="someField1">Field #1</label>
        <input type="text" id="someField1" />
    </p>

    <p>
        <label for="someField2">Field #2</label>
        <input type="text" id="someField2" />
    </p>

    </fieldset>

    <p>
        <input type="submit" value="Submit" />
    </p>

</form>

Working example

I also have a simple example that you can try here:

Problem

On your iPad, follow these instructions:

• Go to the above URL.
• Click in the first window of the first form, but do not enter anything, just show it to the keyboard.
• Press "next" on the keyboard, this will lead you to the choice, again it should set the parameter, but do not select anything.
• Click Next again, so now you had to move from the selection to the first field in the second form.

"next" ? , , .
