I like the features of the “Image Overlay” block where I can change the color of markers based on the signal status. Since the positioning must be based on where the markers are compared to the image used, I’m guessing I can not get rid of the (+|-) zoom button in this block, right? The reason of me asking is that in this particular dashboard, I don’t need an image to overlay on, I just need 8 lines of label text, where a marker , next to the text,would change color based on signal status. Is there maybe another block that would be better suited for this? ---

What data is backing your 8 lines of text? For example, does each line represent a different attribute of the same device? Or is each line a different device indicating the value of attribute? Or is it a mix of the two? ---

Each line of text is static description of an Alarm. The color change is based on an alarm bit (0 or 1) from an attribute ---

And are those 8 different attributes of one device, or 8 devices all with the same attribute? The answer to that question could change my recommendation on how you could get the behavior you seek. ---

One device , 8 attributes. ---

In that case, short of using the [Custom HTML Block](https://docs.losant.com/dashboards/custom-html/), I don’t have a perfect solution to get you what you’re looking for; however, I can think of a couple workarounds … If the dashboard in question is being used in an application experience, you could write some custom CSS to hide the +/- buttons in the image overlay. However, I do not recommend that as users could still zoom the block using their mouse / trackpad, and the absence of buttons to reset their zoom could lead to a bad experience. You could also try using the [Input Controls Block](https://docs.losant.com/dashboards/input-controls/) to get something akin to what you’re looking for. In the attached screenshot, I’m using a combination of [help blocks](https://docs.losant.com/dashboards/input-controls/#help-blocks) alongside [toggle switches](https://docs.losant.com/dashboards/input-controls/) whose default values are [dynamically set by query](https://docs.losant.com/dashboards/input-controls/#dynamic-default-values). The downside is the user could unlock the block and change the value of the toggles, but in the absence of a button in the input controls block, they can’t really cause any damage. ![Screen Shot 2020-03-27 at 9.02.11 AM](https://us1.discourse-cdn.com/flex015/uploads/getstructure/original/2X/8/80c13b1e359b9973bfaa7d57afcc5e05ed40ebfb.png) ---

Understood. Would the input toggle switches refresh with dashboard auto refresh, or does the whole page need to be refreshed? ---

The toggle switches will update whenever the dashboard data refreshes. No whole-page-refresh needed.
