# Advanced Layout

You can use the layout-header slot and the layout-body slot to define advanced header and record layouts.

For example:

<div class="demo-grid middle">
  <c-grid
    :data="records"
    :frozen-col-count="1">
    <template slot="layout-header">
      <!-- header line1 -->
      <c-grid-layout-row>
        <c-grid-header width="85" rowspan="2">ID</c-grid-header>
        <c-grid-header
          width="20%"
          min-width="150"
        >
          First Name
        </c-grid-header>
        <c-grid-header width="200" rowspan="2">Birthday</c-grid-header>
      </c-grid-layout-row>
      <!-- header line2 -->
      <c-grid-layout-row>
        <c-grid-header
          width= "20%"
          min-width="150"
        >
          Last Name
        </c-grid-header>
      </c-grid-layout-row>
    </template>
    <template slot="layout-body">
      <!-- line1 -->
      <c-grid-layout-row>
        <c-grid-column field="personid" width="85" rowspan="2"/>
        <c-grid-input-column
          field="fname"
        />
        <c-grid-column :field="getBirthday" rowspan="2"/>
      </c-grid-layout-row>
      <!-- line2 -->
      <c-grid-layout-row>
        <c-grid-input-column
          field="lname"
        />
      </c-grid-layout-row>
    </template>
  </c-grid>
</div>
