A method performed in a user interface, UI, of a process control system, the UI being configured to be displayed on an electronic visual display unit connectable to the process control system, the UI being adapted to visually indicate a plurality of components (101a-101h, 204-206) included in at least a part of a process controlled by the process control system, each component of the plurality of components (101a-101h, 204-206) being associated with a set having a plurality of elements (211 a, 212a, 213a, 214a), each of which elements is associated with operation of the component, the method comprising: generating at least one sub-UI (210a, 210b), each sub-UI corresponding to a respective component of the plurality of components and each sub-UI (210a, 210b) being adapted to controllably visually indicate at least some of the elements (211 a, 212a, 213a, 214a) of the set associated with the corresponding component, and to enable the user to control the operational state of the corresponding component (101a-101h, 204-206) by means of user input provided to the sub-UI (210a, 210b); displaying the at least one sub-UI (210a, 210b) on the display unit, the method being characterized by the step of adapting each of the at least one sub-UI (210a, 210b) such that the number of elements visually indicated in each sub-UI (210a, 210b) when the at least one sub-UI is displayed on the display unit depends on the number of sub-Uls (210a, 210b) that are displayed on the display unit at the same time, such that, for each of the at least one sub-UI (210a, 210b), the number of available operations that can be performed on the corresponding component (101a-101h, 204-206) by means of user input provided to the sub-UI (210a, 210b) depends on the number of sub-Uls that are displayed on the display unit at the same time, wherein the number of elements visually indicated by one or more of the at least one sub-UI (210a, 210b) decreases with an increasing number of sub-Uls (210a, 210b) that are displayed on the display unit at the same time. generating at least one sub-UI (210a, 210b), each sub-UI corresponding to a respective component of the plurality of components and each sub-UI (210a, 210b) being adapted to controllably visually indicate at least some of the elements (211 a, 212a, 213a, 214a) of the set associated with the corresponding component, and to enable the user to control the operational state of the corresponding component (101a-101h, 204-206) by means of user input provided to the sub-UI (210a, 210b); displaying the at least one sub-UI (210a, 210b) on the display unit, the method being characterized by the step of adapting each of the at least one sub-UI (210a, 210b) such that the number of elements visually indicated in each sub-UI (210a, 210b) when the at least one sub-UI is displayed on the display unit depends on the number of sub-Uls (210a, 210b) that are displayed on the display unit at the same time, such that, for each of the at least one sub-UI (210a, 210b), the number of available operations that can be performed on the corresponding component (101a-101h, 204-206) by means of user input provided to the sub-UI (210a, 210b) depends on the number of sub-Uls that are displayed on the display unit at the same time, wherein the number of elements visually indicated by one or more of the at least one sub-UI (210a, 210b) decreases with an increasing number of sub-Uls (210a, 210b) that are displayed on the display unit at the same time.
