I think I'm misunderstanding how elements works..

HTML code:

```
<div id="div-item">
    <a href="#">A link</a>
    <form>
        <div>
            <select>
                <option>1</option>
                <option>2</option>
            </select>
        </div>
    </form>
</div>

```

When I do this:

```
element(by.tagName('select')).all(by.tagName('option')).count();

```

This gives me 2, which is correct

When I do this:

```
element(by.id('div-item')).element(by.tagName('select')).all(by.tagName('option')).count();

```

This gives me 0. I thought chaining elements finds sub-elements. Is this not correct? How do I restrict the .all(by.tagName('option')) only within this div, rather than the whole page?

This is the xeditable library. My HTML code is:

```
<div id="div-item" class="col-xs-3">
    <a id="xeditable-link" href="#" ng-if="canEdit"
       editable-select="user_id"
       e-ng-options="user.id as user.name for user in users"
       onbeforesave="updateProfile({user_id: $data})">
       {{ showNameFromID(user_id) || 'none'}}
    </a>
</div>

```

But this generates a lot of HTML code. It's something like:

```
<div id="div-item" class="col-xs-3">
    <a id="xeditable-link" href="#" ng-if="canEdit"
       editable-select="user_id"
       e-ng-options="user.id as user.name for user in users"
       onbeforesave="updateProfile({user_id: $data})">
       {{ showNameFromID(user_id) || 'none'}}
    </a>
    <form ...>
        <div class="xeditable-controle..." ...blah blah>
            <select ...ng-options="..." blah blah>
                <option>1</option>
                <option>2</option>
            </select>
            <span> ...the buttons... </span>
        </div>
    </form>
</div>

```

My test spec: 

```
it('should pass ...', function() {
    element(by.id('xeditable-link')).click(); // Click the link to bring up xeditable
    element(by.tagName('select')).click();    // Click the select to bring up the popup
    var allOptions = element(by.id('div-item')).element(by.tagName('select')).all(by.tagName('option'));
    expect(allOptions.count()).toBe(2);
    for (var i = 0; i < 2; ++i) {
        expect(allOptions.get(i).getText()).toBe(testText[i]);
    }
});

```

Both of the expect statements fail. count is 0, instead of 2 and "NoSuchElementError: No element found using locator: By.tagName("select")"
