h3. Example
{code:javascript}
var findColIndex = function (item, layout) {
    return fluid.find(layout.columns,
                      function (column, colIndex) {
                          return item === column.container? colIndex : undefined;
                      });
};

{code}
The function {{findColIndex}} uses {{fluid.find}} to examine a list of columns. The anonymous function being passed as the second argument compares each column's {{container}} property against the desired {{item}} and returns the index of the column if it matches. {{fluid.find}} will apply this function to each item in the column list and return the first column that matches.
