Run Jupiter Notebook Interact inside a Tab widget

I would like to have an interact function/widget inside a tab. For example, once the user activates a particular checkbox, other widgets will appear in that Tab. This is an example of what I have done so far:

import ipywidgets as widgets

def initial_condition(Turn_on_IC): 

# this is the function that "generates" the initial condition
# text-boxes if the user turns on the IC checkbox

    if Turn_on_IC == True:
        label_iniCond = widgets.HTML("""The Initial elevation file dictates the 
             dry/wet zones of the bathymetry. The initial U and V velocity files specifies 
            the velocities in the x and y directions. They must be uploaded in 
            the Jupyter Notebook Home folder before running the simulation.""",
            layout = widgets.Layout(height = '45px', width = '90%',
                        size = '20'))
        
        space_box = widgets.Box(layout=widgets.Layout(height ='25px', width='90%')) 
# this ^ box is created to have space among widgets 

        # initial elevation widget container (label and textbox)
        label_iniElev = widgets.Label('Initial Elevation Text File:',
        layout =  widgets.Layout(width = '18%'))
        iniElev_text = widgets.Text(layout=widgets.Layout(width = "50%",height = '85px'))
        container_iniElev = widgets.HBox(children=[label_iniElev,iniElev_text])

        # initial u vel widget container (label and textbox)
        label_Uvel = widgets.Label('Initial U Velocity Text File:', 
        layout = widgets.Layout(width = '18%'))
        Uvel_text = widgets.Text(layout = iniElev_text.layout)
        container_Uvel = widgets.HBox(children=[label_Uvel,Uvel_text])

        # initial v vel widget container (label and textbox)
        label_Vvel = widgets.Label('Initial V Velocity Text File:', 
        layout = widgets.Layout(width = '18%'))
        Vvel_text = widgets.Text(layout = iniElev_text.layout)
        container_Vvel = widgets.HBox(children=[label_Vvel,Vvel_text])

        iniCond_box = widgets.VBox(children=[label_iniCond,space_box,container_iniElev,
                                    container_Uvel,container_Vvel])
        return(iniCond_box)
    else: 
        iniCond_box = widgets.VBox(children=[])
        return(iniCond_box)
    
iniCond = interact(initial_condition, Turn_on_IC=False) 

I’m calling the function with interact and the function works well if you run it like this…but as soon as I add it to a tab, it doesn’t. It displays this error message: ValueError: Can’t clean for JSON: <function initial_condition at 0x114f23268>

Also, if I use interactive instead of interact the checkbox appears in the tab, but the function does not work. I’ve ran out of ideas, does anyone know how could I solve this?

Thanks a lot for answering so fast! I’m sorry for not explaining myself better. I’m creating a GUI capable of generating a simple bathymetry, an input file and finally run and post process a wave model. So each tab would be a step of that procedure. I’ve attached an image of my GUI so far. The example I gave before belongs to the “Initial condition” tab seen in the image. Once the user press the checkbox, the input file will have a ‘true’ (hence why that option can’t be a accordion) on the option of uploading initial conditions. I would like for the text-boxes to appear if the user presses the checkbox to limit what the user would input to the input file. If he doesn’t want to add initial conditions, then he shouldn’t have the possibility to write/edit anything else in that part. The second option you gave is more similar to what I’m working with, but it still does not appear inside a tab. Hopefully now that I’ve explained the issue better, you could help 😃 Thanks in advance!
