&DD<drop down name>

Processes the field to be a drop down. Data for the drop down is handled by your LANSA Web function.

This tag can be extended manually by using the SIZE, SPLIT and OFFSET attributes.

The SIZE attribute allows you to visualize the drop down as a list box. The OFFSET and SPLIT attributes allow you to manipulate the presentation of the data.

The example below is a list box for the DEPTMENT field. It instructs LANSA for the Web to apportion the first 4 characters as the VALUE to return to the program. Since the SPLIT keyword is used, the description displayed in the list box is the text offset by 4.

<RDML MERGE="&DDD01" FIELD="DEPTMENT" OFFSET="4" SPLIT SIZE="5">

An optional attribute for this tag is the FORMAT keyword. This attribute allows you to format the row number. For example,

<RDML MERGE="&ROWNUM" FORMAT="4">

instructs LANSA to format the row number as a 4-digit string, padded with leading zeros, if necessary.

Typically, this tag is used if you want to configure your own browse list component with an appropriate name. In this case, the NAME attribute of your component would be:

NAME="__<field name>-<RDML MERGE="&ROWNUM" FORMAT="4"> D"

where <field name> is the name of the field padded with trailing blanks up to 10 characters.

For an example, refer to the SET Collection.
