element description
your-class name of the class after which we want to add support for showing/hiding text, list or table
data-config embedding JSON in the html, the entire configuration of a particular element
type we have three type after which it will be hidden [text, list or table]
limit text after how many characters to hide the text and insert show more/less
list or table after how many elements/rows hide the rest and insert show more/less
after this parameter checks how much text is after the trimmed text the limit parameter, if the text is less than the after parameter does not add a more/less button`^.
element on the parameter we will create an html element and put in the text show more/less
more/less is the text and chars that appears after the text, list or table e.g. > show more and < show less
number number of hidden items to show more/less e.g. -> show more 3, only works for list and table
ellipsis show only the ellipsis
onAction callback function

^ Let's say we have 20 records with text and we determine that the text is to be trimmed after 100 characters in each record, it may happen that in several records the text is very short and has 110 characters, so show more/less will appear after 100 characters and after clicking an additional 10 characters, it will look funny. To prevent this, we add the "after": 50 parameter, which means that the hidden text must be at least 50 characters. Otherwise, show more/less will not appear. The same after can be applied to lists, elements and table records

Number of records counted in the table tr based on all tr of thead, tbody and tfoot

Callback function

document.addEventListener('DOMContentLoaded', function() {
  // text, table, list, elelemnts
  new ShowMore('.element', {
    onAction: (type, object) => {
      // type = less/more and full object
      console.log(type, object);
