    10 layouts</title><prolog><metadata><keywords></keywords></metadata></prolog><conbody>

    11 <p>List items can in general be more complex (contain more elements) than

    12 grid items. Certain layout rules apply to all lists:</p>

    13 <ul>

    14 <li><p>All items in a list have equal height on the screen (forms do not follow

    15 this rule in the Edit state, see <xref href="GUID-1AA32C40-CDE0-4627-A634-7C07BB1ED67B.dita">Forms</xref>). </p></li>

    16 <li><p>The column structure of all items in a list must be similar. It is

    17 not possible to combine e.g. single-column items to a three-column item list

    18 (however, it is possible to use some different item types having the same

    19 general appearance), see <xref href="GUID-F95A7D74-FD5C-40D2-BF4F-2F75443CAE51.dita">Column

    20 structure of lists</xref> for columns. </p></li>

    21 <li><p>Partial items are not visible: when the list/grid pane area does not

    22 exactly correspond to an integer number of items, the remaining area outside

    23 the last fully visible item appears empty, displaying the background of the

    24 particular pane.</p></li>

    25 </ul>

    26 <p>In landscape layout, all two row lists can be stretched to be displayed

    27 in one row. This enables displaying more items in the list. In list stretching,

    28 the second row is moved next to the first row. List stretching is ON by default,

    29 but application can decide to disable it.</p>
