How elements are used in Chameleon
One of the most powerful aspects of Chameleon is being able to show users specific parts of your interface to help them discover and use important functionality.
Examples of this include:
position a tour step by snapping it to an element on the page;
highlight a particular element;
fire a click on an element when a user clicks the "Next" button in a step;
require an element to be clicked to proceed to the next step of the tour;
track clicks and use them for targeting tours; and more.
All these cases require Chameleon to correctly identify and save the relevant element on the page. This is something our technology is built to handle, but in some cases it's useful to know how it works, in case you need to make a manual adjustment.
CSS selectors are key
Chameleon identifies the element you have selected (using the point-and-click editor) using CSS Selectors: these are code identifiers that target an HTML component on the page.
In the image above, "body" is the CSS Selector, but there are many more, but some of the most common include the element selector (e.g. <div>, <p> etc.), <class> and <id>. Together these can help uniquely identify an element on the page.
How to select an element in Chameleon
Note: The above video displays an outdated version of Chameleon's interface. It has been replaced to give our users a more intuitive and pleasing experience. We will soon create new videos to showcase our new UI 🙂
In Chameleon whenever there is the opportunity to Select element then you will see the same point-and-click flow. The selected element will then have a purple outline appear around it.
Normally this will correctly identify and save the element you have clicked on, but in some cases, you may not see the correct element highlighted (with the purple outline) or the match may be incorrect if you return later.
In these cases, it might be necessary to manually Adjust selector to refine the CSS Selectors to accurately and reliably match the intended element.
The Adjust selectors config box will give you two broad ways to input the correct selectors:
Adjust single selectors
Add custom CSS path
As you adjust the CSS Selectors, the matching will be updated in real-time and the matching element will show the purple outline. You can use this as a guide to check whether you've made the correct adjustments to match the intended element.
1. Adjusting single selectors
This option allows you to easily edit or add an individual selector to help you define the right element.
For example, you may want to use 'HTML Hierarchy' and you can check the box, or you may want to change the 'text' value or add an additional 'id'. You can do all that easily here.
The available options to adjust how this element is selected are:
HTML hierarchy: all of html tags from this element up to the
<body>tag. This helps us locate the element on the page and typically consists of
<div>tags and their classes.
tag: the type of html tag associated with this specific element, such as
text: the text string this element contains, such as "Sales by day"
id: the unique ID, such as "chart-overview-1234"
class: any class names, such as "chart-main"
href: any link associated, such as "https://www.trychameleon.com"
title: the title, such as "Chart"
type: the type, typically found on
<input>fields, such "text" or "email"
name: the name, such as "Top sales"
2. Adding a custom CSS path
You can also fully edit the CSS path to identify the correct element. This is great if you have technical support or need a unique or very custom configuration for your selector.
To use this, simply select the radio box adjacent to the Add custom CSS path title and add your CSS code here.
Selecting multiple elements
It's not currently possible to select multiple elements together for highlighting or for other use cases. However, in some cases*, you can generalize the element selection so that it matches multiple elements, and any of these individually can be used.
You can generalize by adjusting the selectors (e.g. removing specifying criteria such as
href of any element) once the element has been selected.
In the following cases, when multiple elements match, the first matching element will be used.
"Require element on page" (learn how this works here)
Show Step "On hover" or "On click" of an "Icon" / "Label" / "Custom icon"
Position the Step "Anchor to Trigger element" (if "Icon" / "Label" / "Custom icon" used)
Position the Step "Anchor to other element"
Defined events (used for targeting or conversion tracking)
Button action "Click element"
Note: this is because when the icon/label/custom icon or Step needs to display immediately upon page load, a fixed element is required.
However in the following cases, when multiple elements match, you can choose to use only the first or any elements that match:
Show Step "On hover" or "On click" of an "Existing element"
Position the Step "Anchor to Trigger element" (if "Existing element" used)
Complete Experience by clicking "Specific element"
You can use this to allow a user to click/hover on any one of many elements before the Step appears, adjacent to that element, or by allowing them to click any one of a number of elements to advance from the current Step.
Finding the selectors for an element
To uncover what CSS selectors are used for a particular, you can "Inspect" the element, after right-clicking on that element. The HTML content and related CSS Selectors are then shown in the browser's console, as below.
💡 Tip: the value fields use a contains match -- so you can use a subset of the actual value of the field to help identify it.
Dynamically changing selectors
In some cases selector values (e.g. for class name) change each time the application is deployed. This means that the selector values are not persistent, and so the element selection may not continue to match.
If this happens for your application (relevant for some React apps) then you can uncheck the dynamic / changing selectors (such the html hierarchy) from the element match criteria.
You can ask your developer for help here, or wait for the application to be updated (before publishing a tour) and then make an adjustment.
Use trial-and-error to uncheck selectors that might be the culprits (we suggest starting with html hierarchy and class). If removing these conditions causes the element to be matched again, a green border around that matching element will reappear on the page.
