Hello there!

I'm looking for a way to have links to some of the outputs in Index Unit but not all, only the ones with certain attribute (for example: name = "enric").

Is there any way to do that? Create some kind of filter where the link will be applied?

Hello,

you can also use the Indexed Visibility Condition which permits you to display links only in case of specific conditions (in your case: "name" attribute == "enric").

For more details and an example refer to: Help -> WebRatio Release Notes -> Indexed Conditions paragraph

In your case:

1) Add a Page Variable (right click on the Page -> Add -> Variable) which refers to the desired attribute of the Index Unit.

2) Add a Condition Expression (right click on the Page -> Add -> Condition Expression) working on the previous defined Variable. The Expression defines the value of the variable to be considered for the visibility. E.g. var2 == "enric".

3) Apply the Visibility Condition to the Index Unit. Select the Index Unit in the Grid and in the Properties Panel -> Condition tab -> set the Link Visibility Cond. property to the previous defined condition.

If you apply a custom unit template, you have to update it by adding the "position" attribute to the "wr:Visible" tags that are used inside loops over data.

....
<c:forEach var="current" varStatus="status" items="${<wr:UnitId/>.data}">
....
  <wr:Visible context="......" position="'index'">
  ....
  </wr:Visible>
....
</c:forEach>
....

Hello,

if you wish to display links only for specific outputs of the Index Unit you could customize the template of the Index Unit. You have to add a condition for printing the link only if the value of an attribute (e.g. "name") is equal to the desired one (e.g. "enric"). This condition encloses the code which prints the link in the page. For example:

....
<c:forEach var="current" varStatus="status" items="${<wr:UnitId/>.data}"> // iterates on the Index Unit data
  ....
  ....
  <c:if test="${current.name=='enric'}">  // the link is printed if the value of the 
                                          // "name" attribute is "enric"
    <wr:Link class="link"/>
  </c:if>
  ....
</c:forEach>
....
