You can conditionalize inline elements, such as uicontrol, wintitle, and cite. But do not tag a word or group of words with <ph> to apply a condition because it can cause major issues.
Procedure
Check out the topic.
Place the cursor inside the tag to which you want to apply the condition.
In Oxygen XML Author, click SDL Tridion Docs > Conditional text > Set condition.
The page displays the Condition Builder dialog box.
If no conditions are listed on the Conditions tab of Condition Builder, or if the condition that you need to apply is not listed:
Click the Tree tab.
In the left pane, expand All Condition Names, and then select the category of conditions that you need to apply, such as otherprops and Product.
The conditions in the selected category are displayed in the right pane of the Tree tab.
Select the required condition, and then click Add.
On the Condition tab, select the condition that you want to apply, and then click OK.
To apply more than one condition, press and hold down Ctrl while selecting all conditions to apply, click Or, and then click OK.
Check in the topic.
In the Content tab of Publication Manager, preview the topic in the right pane to validate that the element where you added the condition shows with either red or green highlighting.
Next Steps
In the Conditions tab of the publication, select the appropriate condition.
Publish the output and verify if the conditionalized text is visible or hidden based on what you set in the Conditions tab.
